1. The White Screen of Death (WSOD)
What it is:
The White Screen of Death is one of the most infamous WordPress errors. When this happens, your website simply displays a blank white page, with no error message to help you figure out what’s wrong.
How to fix it:
- Deactivate Plugins: Access your site via FTP or cPanel and navigate to the
wp-contentfolder. Rename the “plugins” folder to “plugins_old”. If the site works after this, reactivate plugins one by one to identify the culprit. - Switch to a Default Theme: If the plugins aren’t the issue, try switching to a default WordPress theme (e.g., Twenty Twenty-Three). This can help rule out theme-related issues.
- Increase PHP Memory Limit: Sometimes, this error can be caused by a lack of server resources. Increase your PHP memory limit by adding the following line to your
wp-config.phpfile:define('WP_MEMORY_LIMIT', '256M');
2. Internal Server Error (500 Error)
What it is:
The 500 internal server error is a generic error that usually appears when there is a problem with your server configuration or scripts.
How to fix it:
- Check .htaccess File: A corrupt
.htaccessfile is often the cause. Rename it to.htaccess_oldand then try accessing your site again. If this resolves the issue, generate a new.htaccessby going to Settings > Permalinks and saving changes. - Increase PHP Limit: Edit the
php.inifile or yourwp-config.phpfile to increase the PHP memory limit. - Check for Plugin or Theme Conflicts: Deactivate all plugins, and switch to the default theme. Reactivate them one by one to identify the source of the issue.
3. Error Establishing a Database Connection
What it is:
This error indicates that WordPress cannot connect to the database. It may be caused by incorrect database credentials or server issues.
How to fix it:
- Check
wp-config.php: Ensure the database name, username, password, and host are correct. You can verify these credentials with your hosting provider. - Repair the Database: Add the following line to your
wp-config.phpfile to enable WordPress database repair:define('WP_ALLOW_REPAIR', true);
Visityourdomain.com/wp-admin/maint/repair.phpto repair the database.
4. 403 Forbidden Error
What it is:
This error occurs when your server refuses to fulfill a request. It usually happens due to incorrect file permissions or security plugin settings.
How to fix it:
- Check File Permissions: Ensure your WordPress files have the correct file permissions (755 for directories, 644 for files).
- Deactivate Security Plugins: Temporarily deactivate any security plugins and see if the issue persists. If it resolves, check your plugin’s configuration.
- Clear .htaccess: Delete or rename your
.htaccessfile and refresh your site. WordPress will generate a new one.
5. 404 Not Found Error
What it is:
The 404 error happens when a page or post is missing or the URL is incorrect.
How to fix it:
- Reset Permalinks: Go to Settings > Permalinks, and simply click “Save Changes” to reset your permalink structure.
- Check for Missing Content: Ensure that the post or page exists in your WordPress dashboard and is not set to private.

What it is:
This error typically happens when your server takes too long to respond.
How to fix it:
- Increase PHP Memory Limit: Add
define('WP_MEMORY_LIMIT', '256M');to yourwp-config.phpfile. - Check Hosting Resources: If you’re on shared hosting, your resources might be too limited. Consider upgrading to a VPS or dedicated server.
- Disable Plugins and Themes: Disable any plugins that might be causing the delay, or switch to the default WordPress theme to see if the issue resolves.
7. Sidebar Below Content
What it is:
This issue occurs when the sidebar of your WordPress site appears below your content instead of beside it. It is usually caused by a CSS or HTML problem.
How to fix it:
- Check Theme’s CSS: Inspect the CSS code, especially the theme’s
style.css, to identify broken or conflicting styles. - Fix HTML Markup: Ensure that all HTML elements are correctly closed, especially
<div>and<ul>tags. - Deactivate Plugins: Sometimes, plugins can modify your theme’s layout. Deactivate them to check for conflicts.
8. WordPress Auto-Update Failed
What it is:
Occasionally, WordPress fails to automatically update to the latest version, leaving you with an outdated site and potential security vulnerabilities.
How to fix it:
- Manual Update: If auto-update fails, download the latest WordPress version from wordpress.org. Extract the files and overwrite the files in your server via FTP.
- Check File Permissions: Incorrect file permissions can prevent WordPress from updating. Ensure that the
wp-contentfolder is writable.
9. WordPress Stuck in Maintenance Mode
What it is:
When WordPress is updating and the process is interrupted, it can leave your site in a “maintenance mode” state, showing an error message that the site is undergoing maintenance.
How to fix it:
- Delete the
.maintenanceFile: Access your site via FTP or cPanel and delete the.maintenancefile in your website’s root directory. This will remove the maintenance mode. - Clear Browser Cache: After deleting the file, clear your browser cache and try reloading the site.
10. White Screen after Installing a Plugin or Theme

wp-content/pluginsorwp-content/themesfolder, and rename the plugin or theme folder that caused the issue. - Check for Compatibility Issues: Before installing plugins or themes, ensure they are compatible with your current version of WordPress.
