Most Common WordPress Errors and How to Fix Them

WordPress is a fantastic platform, but like any technology, it’s not without its quirks. Errors are a part of website management, and they can happen for a variety of reasons—whether it’s a plugin conflict, a server-side issue, or something related to your theme or settings. The good news is that most WordPress issues are solvable with some basic troubleshooting and adjustments.

At WebAllWays, we’ve been helping clients resolve WordPress issues for over a decade. In this comprehensive guide, we’ll go through 50 common WordPress errors and provide detailed, actionable solutions to resolve them. Whether you’re dealing with a database connection error, a blank page, or slow page loads, we’ve got you covered.

1. White Screen of Death (WSOD)

What is it?
The White Screen of Death occurs when your website shows a completely blank screen instead of content. This issue can be caused by a plugin, theme conflict, or PHP memory issues.

How to Fix It:

Deactivate Plugins: A faulty plugin is often the culprit. Use FTP or File Manager to navigate to the wp-content directory. Rename the plugins folder to something like plugins_old to disable all plugins. If your site comes back, reactivate plugins one by one to identify the problematic one.
Switch to a Default Theme: The issue could also be caused by your theme. Go to the wp-content/themes folder and rename the active theme’s folder. WordPress will automatically activate a default theme, such as Twenty Twenty-One.
Increase PHP Memory: Add this line to your wp-config.php file to increase the PHP memory limit:
define('WP_MEMORY_LIMIT', '256M');
This can solve issues related to low memory.

2. Error Establishing a Database Connection

What is it?
This error occurs when WordPress cannot connect to your database, usually due to incorrect database credentials or a server issue.

How to Fix It:

Check Database Credentials: Open your wp-config.php file and check the database name, username, password, and host. Ensure these details are correct and match the ones provided by your hosting provider.
Repair the Database: Add the following line to your wp-config.php file to enable database repair mode:
define('WP_ALLOW_REPAIR', true);
Visit http://yoursite.com/wp-admin/maint/repair.php to repair the database.
Contact Your Host: If the above steps don’t fix the issue, it’s possible that there’s a server-side issue. Contact your hosting provider for assistance.

3. 404 Page Not Found Error

What is it?
This error occurs when visitors try to access a page that doesn’t exist or is no longer available, causing a “Page Not Found” message.

How to Fix It:

Check Permalinks Settings: Go to Settings > Permalinks in your WordPress dashboard and click “Save Changes” without making any changes. This will refresh your permalink structure.
Ensure Pages Are Published: Sometimes, pages are in “draft” mode or deleted unintentionally. Double-check that your pages are published.
Set Up 301 Redirects: If you’ve changed your URL structure, use the Redirection plugin or add 301 redirects in your .htaccess file to direct users to the correct pages.

4. Internal Server Error (500)

What is it?
A generic error message, often indicating a server issue. The problem could be caused by a plugin, theme, or server configuration issue.

How to Fix It:

Disable Plugins: Deactivate all plugins by renaming the plugins folder to plugins_old via FTP. If your site works after this, reactivate plugins one at a time to find the culprit.
Switch to a Default Theme: If disabling plugins doesn’t help, try switching to a default theme (like Twenty Twenty-One) to rule out theme-related issues.
Increase PHP Limits: Add the following code to your wp-config.php file to increase PHP limits:
define('WP_MEMORY_LIMIT', '256M');
Check Error Logs: Access your server logs through your hosting account or via cPanel to pinpoint the cause of the error.

5. Briefly Unavailable for Scheduled Maintenance

What is it?
This error happens when WordPress is stuck in maintenance mode, usually after an automatic update.

How to Fix It:

Deactivate Plugins: Some plugins are resource-intensive and may contribute to this error. Try deactivating plugins and switching themes to reduce the memory load.

7. Failed to Write to Disk Error

What is it?
WordPress is unable to upload files due to a lack of write permissions.

How to Fix It:

Check File Permissions: Navigate to your wp-content/uploads folder and ensure that it has the correct permissions. Directories should have permissions set to 755, while files should have permissions set to 644. You can change permissions via FTP or cPanel File Manager.
Contact Your Hosting Provider: If you’re unable to change permissions, contact your hosting provider for help.

8. Too Many Redirects Error

What is it?
This error occurs when there’s an infinite loop of redirects, typically due to incorrect URL settings or conflicts between plugins.

How to Fix It:

php_value max_execution_time 300
Contact Hosting Provider: If you’re unable to increase the limit, contact your hosting provider and ask them to adjust the upload file size limits.

11. Syntax Error

What is it?
A syntax error occurs when there is a mistake in the code, such as a missing parenthesis, semicolon, or bracket.

How to Fix It:

Check Error Message: WordPress typically shows the file and line number where the error occurred. Navigate to that file via FTP and correct the syntax error (e.g., add missing punctuation).
Revert to a Backup: If the error is complex and you can’t figure it out, revert to a recent backup of your site.

Delete the .maintenance File: Navigate to your website’s root directory using FTP or File Manager in your hosting account. Find for the .maintenance file and remove it. This will remove WordPress from maintenance mode.
Check for Update Conflicts: If the issue happens repeatedly, check the update logs and ensure plugins or themes aren’t conflicting during updates.

17. The “This Site Can’t Be Reached” Error

What is it?
This error typically occurs due to DNS issues or a connectivity problem, which prevents your browser from accessing the site.

How to Fix It:

Check DNS Settings: Ensure that your domain is pointing to the correct DNS servers. You can verify this by checking your DNS settings in your hosting provider’s dashboard.
Flush DNS Cache: On your local computer, flush your DNS cache by typing ipconfig /flushdns into the command prompt (Windows) or terminal (macOS).
