How to Fix Internal Server Error in WordPress – ITXperts Guide
The Internal Server Error is one of the most frustrating issues you can encounter as a WordPress user. This generic error doesn’t provide much insight into the actual problem, which can make troubleshooting tricky. However, with the right approach, you can resolve the issue and get your site back up and running.

In this blog post, ITXperts will walk you through the common causes of the Internal Server Error and provide a step-by-step guide to fixing it.

What Causes the Internal Server Error in WordPress?

The Internal Server Error, often referred to as a “500 Internal Server Error,” can be caused by several factors, including:
- Corrupted .htaccess file: This is a common issue, especially after updates or changes to your site’s structure.
- PHP memory limit issues: WordPress sometimes requires more memory than your server provides, causing the error.
- Plugin or theme conflicts: Faulty or incompatible plugins or themes can cause the server to misbehave.
- Corrupt core files: In some cases, the WordPress core files may become corrupt due to an incomplete update or malware.
- Server misconfiguration: Server-related issues, like permission errors or an overloaded server, can also trigger this error.
Now that we know the causes, let’s explore how to fix the problem.

Steps to Fix the Internal Server Error in WordPress

1. Check for a Corrupted .htaccess File

One of the most common causes of an Internal Server Error in WordPress is a corrupted .htaccess file. Here’s how you can fix it:
1. Access your website files: You can use FTP (like FileZilla) or your hosting provider’s file manager.
2. Locate the .htaccess file: This file is in your website’s root directory (where WordPress is installed).
3. Rename the file: Rename the .htaccess file to something like .htaccess_old. This will disable it.
Now, try loading your site. If it works, the issue was with the .htaccess file. To generate a new, clean version of the .htaccess file:
1. Go to your WordPress dashboard.
2. Navigate to Settings > Permalinks.
3. Click Save Changes (you don’t need to modify anything). This will automatically regenerate the .htaccess file.
2. Increase PHP Memory Limit

The Internal Server Error can also occur if your WordPress installation exceeds the PHP memory limit. Increasing the PHP memory limit can fix this problem.

Here’s how:
1. Edit wp-config.php: Access the wp-config.php file from your root directory.
2. Add the following line right before the “That’s all, stop editing!” comment:
```
define( 'WP_MEMORY_LIMIT', '256M' );
```
This increases your memory limit to 256 MB, which should be sufficient for most WordPress installations.

3. Disable All Plugins

If your .htaccess file isn’t the problem and increasing the PHP memory limit doesn’t help, the issue may be caused by a faulty plugin. To check:
1. Access your site via FTP or your hosting control panel.
2. Navigate to wp-content and locate the plugins folder.
3. Rename the folder to something like plugins_old. This will deactivate all the plugins on your site.
Now, try reloading your site. If it loads without the error, the issue lies with one of your plugins. To identify the faulty plugin:
1. Rename the plugins_old folder back to plugins.
2. Activate your plugins one by one and test your site after each activation. This will help you pinpoint the problematic plugin.
Once you’ve identified the faulty plugin, deactivate it or contact the plugin developer for support.

4. Revert to a Default Theme

If disabling plugins doesn’t resolve the issue, your theme might be the cause. You can switch to a default theme (like Twenty Twenty-One) to check if the error persists.
1. Access your site via FTP.
2. Navigate to wp-content > themes.
3. Rename your current theme folder (e.g., mytheme_old).
4. WordPress will automatically switch to a default theme if the active theme folder is missing.
If your site loads properly with the default theme, the issue is with your theme. You can contact the theme developer for assistance or consider switching to a more stable theme.

5. Re-upload Core WordPress Files

Sometimes, the core WordPress files can become corrupted due to incomplete updates or malware attacks. Re-uploading the core files can resolve the issue.
1. Download the latest version of WordPress from WordPress.org.
2. Extract the downloaded ZIP file.
3. Upload the wp-admin and wp-includes folders from the extracted files to your server, replacing the existing folders.
This will not affect your content or themes but will overwrite any corrupted core files.

6. Check File Permissions

Incorrect file permissions can also trigger an Internal Server Error. WordPress recommends the following permissions:
- Files: 644
- Folders: 755
To fix file permissions:
1. Access your website files via FTP or your hosting control panel.
2. Set the file permissions of all files to 644 and folders to 755.
Be careful when adjusting permissions, as incorrect settings can make your site vulnerable to security threats.

7. Contact Your Hosting Provider

If none of the above methods work, it’s time to contact your hosting provider. They can check for server-related issues, such as overloaded resources, server misconfigurations, or even malware attacks that may be causing the error.

Preventing Internal Server Errors in the Future

To prevent future Internal Server Errors, follow these best practices:
- Keep WordPress updated: Always use the latest version of WordPress, plugins, and themes to prevent compatibility issues.
- Backup regularly: Ensure you have a reliable backup solution like UpdraftPlus or Jetpack so you can restore your site easily if something goes wrong.
- Use a high-quality hosting provider: A good hosting provider will ensure your site runs smoothly and will assist with server-related issues promptly.
- Limit plugins: Only install well-coded, necessary plugins, and avoid using too many, as they can increase the likelihood of conflicts.

How to Fix the Error Establishing a Database Connection in WordPress
The “Error Establishing a Database Connection” is one of the most common and frustrating errors WordPress users can encounter. This issue occurs when WordPress is unable to communicate with your website’s database, preventing your content from being displayed. Thankfully, there are several ways to resolve it. In this blog post, we will explore the possible causes of this error and the step-by-step methods to fix it.

What Causes the “Error Establishing a Database Connection” in WordPress?

Before diving into the solutions, it’s essential to understand why this error happens. Some common reasons include:
- Incorrect database login credentials: WordPress requires a correct database name, username, password, and host to connect to the database. If any of these credentials are wrong, the connection will fail.
- Corrupt database: The WordPress database can become corrupted due to various reasons, such as plugin conflicts, database overload, or server crashes.
- Database server is down: Sometimes, the MySQL server hosting your WordPress database might be down, leading to this error.
- Exceeding the database limits: On shared hosting environments, database limits may be exceeded, preventing new connections.
- Corrupted WordPress files: A corrupted WordPress installation or update can break the database connection.
Now that you know the causes, let’s move on to the solutions.

Steps to Fix “Error Establishing a Database Connection”

1. Check Database Credentials

One of the first things you should check when encountering this error is the database credentials stored in the wp-config.php file. Follow these steps:
1. Access your website files: You can access your WordPress files via FTP using software like FileZilla or by using your web host’s file manager.
2. Locate wp-config.php: This file is located in the root directory of your WordPress installation.
3. Verify credentials: Open the wp-config.php file and look for the following lines:
```
define( 'DB_NAME', 'your_database_name' );
define( 'DB_USER', 'your_database_username' );
define( 'DB_PASSWORD', 'your_database_password' );
define( 'DB_HOST', 'localhost' ); // Sometimes it might be different, like an IP address or a custom host.
```
Ensure that the database name, username, password, and host are all correct. You can verify these credentials through your hosting provider’s control panel or by contacting their support team.

2. Repair the WordPress Database

If the database credentials are correct, the issue might be a corrupted database. WordPress has a built-in repair tool that you can use. To enable it:
1. Open your wp-config.php file.
2. Add the following line of code right above the “That’s all, stop editing!” comment:
```
define( 'WP_ALLOW_REPAIR', true );
```
1. Save the file and go to https://yourwebsite.com/wp-admin/maint/repair.php.
You’ll see two options: Repair Database and Repair and Optimize Database. Click the appropriate option and follow the instructions. After repairing, make sure to remove the WP_ALLOW_REPAIR line from wp-config.php.

3. Check the Database Server

If your credentials are correct and the database repair doesn’t work, the issue may lie with the database server. On shared hosting, the MySQL server could be overloaded or temporarily down. Here’s how to check:
1. Test connection from the server: Create a simple PHP file to test the database connection. Create a file called db-test.php and add the following code:
```
<?php
$link = mysqli_connect("localhost", "your_database_username", "your_database_password", "your_database_name");

if (!$link) {
    die("Error: " . mysqli_connect_error());
}
echo "Connection successful!";
?>
```
1. Upload the file to your WordPress directory and access it via your browser (https://yourwebsite.com/db-test.php). If it connects successfully, the database server is not the issue. If it fails, you may need to contact your hosting provider.
4. Update the WordPress Site URL

Sometimes, updating the site URL in the database can fix the error. You can do this via phpMyAdmin:
1. Log in to your hosting control panel and access phpMyAdmin.
2. Select your WordPress database.
3. Navigate to the wp_options table (it may be prefixed differently, like wp7_options).
4. Look for the rows siteurl and home.
5. Edit these values to match your site’s URL, e.g., https://www.yourwebsite.com.
5. Restore from Backup

If none of the above methods work, restoring your website from a recent backup can resolve the error. Most hosting providers offer daily backups, or you may have a backup solution like UpdraftPlus, Jetpack, or similar installed. Restoring the database and files from a previous, working version can fix any corruption or file issues causing the problem.

6. Contact Your Web Host

If you’re still seeing the “Error Establishing a Database Connection” after trying the above steps, it’s time to reach out to your hosting provider. They can help troubleshoot server-related issues, check the MySQL server, and restore any corrupted files or databases.

Preventing Future Database Connection Errors

To prevent this error in the future, follow these best practices:
- Regular backups: Use backup plugins to regularly back up your website. This will allow you to restore it easily in case of an error.
- Update WordPress and plugins: Keep your WordPress installation, themes, and plugins up to date to avoid compatibility issues that may cause database corruption.
- Monitor server performance: If you experience frequent database connection errors, consider upgrading your hosting plan or switching to a more reliable provider.
- Optimize your database: Regularly optimize your database to keep it healthy and avoid performance bottlenecks.
Conclusion

The “Error Establishing a Database Connection” can be alarming, but it’s usually fixable with some troubleshooting. By following the steps outlined above, you should be able to diagnose and resolve the issue quickly. Remember to always maintain a backup of your website, as it can save you time and frustration in situations like this.

List of Common WordPress Errors with Solutions
WordPress is a powerful content management system (CMS) used by millions of websites globally. While it’s user-friendly, users often encounter some common errors that can disrupt the functionality of their site. Fortunately, most of these issues have simple fixes. Below is a list of common WordPress errors and how to resolve them.

1. Internal Server Error (500 Error)

Cause:

This error occurs when there is a problem on the server, but it doesn’t specify what exactly is wrong.

Solution:
- Check for corrupted .htaccess file: Rename the .htaccess file to something like .htaccess_old and reload your website. If the site loads, regenerate a fresh .htaccess by going to Settings > Permalinks and clicking Save.
- Increase PHP Memory Limit: You may need to increase your PHP memory by editing the wp-config.php file and adding this line:
  define('WP_MEMORY_LIMIT', '64M');
- Deactivate Plugins/Themes: Sometimes a plugin or theme is causing the issue. Deactivate all plugins and activate them one by one to identify the faulty one.
2. White Screen of Death (WSOD)

Cause:

This issue is often caused by a theme or plugin conflict or running out of memory.

Solution:
- Disable Plugins: Access your WordPress files via FTP or a hosting file manager. Rename the /plugins/ folder in the wp-content directory to deactivate all plugins. If the site loads, the issue is likely plugin-related. Reactivate each plugin one by one to identify the culprit.
- Switch to Default Theme: Temporarily switch your theme to a default WordPress theme like Twenty Twenty-Three to rule out theme issues.
- Increase PHP Memory Limit: Similar to the internal server error, increase your memory limit as a potential fix.
3. Error Establishing a Database Connection

Cause:

This error occurs when WordPress cannot connect to the database due to incorrect database credentials, a corrupt database, or a database server issue.

Solution:
- Check Database Credentials: Ensure that the database name, username, password, and host in the wp-config.php file are correct:
  define('DB_NAME', 'your-database-name');
  define('DB_USER', 'your-username');
  define('DB_PASSWORD', 'your-password');
  define('DB_HOST', 'localhost');
- Repair the Database: Add the following line to your wp-config.php file to allow database repair:
  define('WP_ALLOW_REPAIR', true);
  Visit http://yoursite.com/wp-admin/maint/repair.php to repair the database.
- Check with Your Host: If none of the above works, contact your hosting provider to ensure the database server is operational.
4. 404 Error on Posts

Cause:

When you get a 404 error on individual posts but your homepage works fine, the problem usually lies with your permalinks.

Solution:
- Reset Permalinks: Go to Settings > Permalinks and click Save Changes to refresh the permalink settings.
- Manually Update .htaccess: If resetting permalinks doesn’t help, you may need to update your .htaccess file. Add this default code to your .htaccess file:
```
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
```
5. Sidebar Below Content Error

Cause:

This usually occurs when HTML/CSS structure is broken due to improper code changes, especially within themes.

Solution:
- Check HTML Structure: Review your theme files, particularly index.php and single.php, for missing or extra div tags.
- Inspect CSS Rules: Incorrect float, clear, or width properties in your CSS could also cause layout issues. Use browser developer tools to diagnose the problem.
- Switch to Default Theme: Temporarily switch to a default theme to see if the issue is theme-related.
6. WordPress Stuck in Maintenance Mode

Cause:

When updating plugins or themes, WordPress automatically enters maintenance mode. If the process is interrupted, it might get stuck in this state.

Solution:
- Delete the .maintenance file: Access your WordPress root directory via FTP or your hosting file manager and delete the .maintenance file. Your site should return to normal.
7. Connection Timed Out

Cause:

This issue is common on shared hosting and occurs due to overloading the server or resource limits being hit.

Solution:
- Increase PHP Memory Limit: As with the previous errors, increasing the PHP memory limit often resolves this issue.
- Optimize Your Website: Disable any resource-heavy plugins or install a caching plugin like WP Super Cache to reduce the load.
- Upgrade Hosting Plan: If you’re consistently running into timeouts, you might need to upgrade to a better hosting plan.
8. Failed WordPress Auto-Update

Cause:

Sometimes automatic updates fail due to server timeouts or permission issues.

Solution:
- Manually Update WordPress: If auto-update fails, you can manually update WordPress by downloading the latest version from the official website and replacing the old core files, except for the wp-content directory.
- Check File Permissions: Ensure that your WordPress files have the correct file permissions. Common permissions are 755 for folders and 644 for files.
9. Memory Exhausted Error – Increase PHP Memory Limit

Cause:

If your website exceeds the allocated PHP memory, you’ll encounter a memory exhaustion error.

Solution:
- Increase PHP Memory: Edit your wp-config.php file and add the following line:
  define('WP_MEMORY_LIMIT', '128M');
- Contact Hosting Provider: If the issue persists, contact your hosting provider to increase the memory limit on the server.
10. Locked Out of WordPress Admin (wp-admin)

Cause:

This could happen due to incorrect login credentials, a plugin conflict, or even a brute force attack.

Solution:
- Reset Password: Use the “Lost your password?” link on the login page. Alternatively, you can reset your password via phpMyAdmin by navigating to the wp_users table and editing the admin user.
- Deactivate Plugins: Disable all plugins using FTP by renaming the /plugins/ folder in wp-content. If you can log in after that, it’s likely a plugin conflict.
- Clear Browser Cache: Sometimes clearing your browser cache or trying a different browser can resolve the issue.
Conclusion

WordPress errors can be frustrating, but most issues have simple solutions. Keeping your WordPress installation updated, using reliable themes/plugins, and maintaining backups will help prevent many common issues. If you ever find yourself stuck, don’t panic. With the right troubleshooting steps, you’ll have your site running smoothly in no time!
