How to Fix Common WordPress Errors Like 404 or White Screen

WordPress is one of the most popular content management systems (CMS) in the world, powering millions of websites. However, like any other software, it’s not immune to errors. In this article, we’ll discuss some common WordPress errors, such as 404 errors and white screens, and provide step-by-step instructions on how to fix them.

Understanding Common WordPress Errors

Before we dive into the fixes, let’s understand what these errors mean:

• 404 Error: A 404 error occurs when a user tries to access a page that doesn’t exist on your website. This can happen due to a deleted page, a changed URL, or a mistyped URL.
• White Screen of Death (WSOD): WSOD is a blank white screen that appears instead of your website. This error can be caused by a plugin or theme conflict, a PHP error, or a database issue.

Fixing 404 Errors in WordPress

404 errors can be frustrating for users and website owners alike. Here are some steps to fix 404 errors in WordPress:

1. Check the URL: Ensure that the URL is correct and properly formatted. A small typo can lead to a 404 error.
2. Verify Page Existence: If you’ve recently deleted a page, make sure it’s not still linked somewhere on your website or in your server’s cache.
3. Update Permalinks: Sometimes, updating your permalink structure can resolve 404 errors. To do this, go to Settings > Permalinks and click “Save Changes.”
4. Check .htaccess File: The .htaccess file plays a crucial role in URL rewriting. If it’s corrupted or incorrectly configured, it can lead to 404 errors. Try resetting the file to its default state.
5. Use a Redirect Plugin: If you’ve changed a page’s URL, use a redirect plugin like Yoast SEO or Redirection to redirect users from the old URL to the new one.

Fixing White Screen of Death (WSOD) in WordPress

WSOD can be caused by various factors, including plugin conflicts, theme issues, or PHP errors. Here are some steps to fix WSOD:

1. Enable Debug Mode: Enable WordPress’s debug mode to identify the cause of the error. To do this, add the following code to your wp-config.php file: define(‘WP_DEBUG’, true);
2. Disable Plugins: Plugin conflicts can cause WSOD. Try disabling all plugins and then reactivating them one by one to identify the culprit.
3. Switch to a Default Theme: A theme conflict can also cause WSOD. Try switching to a default theme like Twenty Twenty-One to see if the issue persists.
4. Increase PHP Memory Limit: A low PHP memory limit can cause WSOD. Try increasing the limit by adding the following code to your wp-config.php file: define(‘WP_MEMORY_LIMIT’, ‘256M’);
5. Check Server Logs: Server logs can provide valuable insights into the cause of WSOD. Check your server logs to identify any errors or warnings.

Other Common WordPress Errors and Fixes

In addition to 404 errors and WSOD, there are several other common WordPress errors that you might encounter. Here are some fixes for these errors:

• Internal Server Error (500): This error can be caused by a corrupted .htaccess file, plugin conflicts, or PHP errors. Try resetting the .htaccess file, disabling plugins, and increasing the PHP memory limit.
• Database Connection Error: This error occurs when WordPress can’t connect to the database. Check your database credentials, ensure the database is running, and try repairing the database.
• Sidebar Below Content: This issue can be caused by a theme or plugin conflict. Try disabling plugins and switching to a default theme to identify the cause.
• Failed to Load Resource Error: This error occurs when a resource (like an image or script) can’t be loaded. Check the file path, ensure the file exists, and try re-uploading the file.

Preventing WordPress Errors

Prevention is better than cure. Here are some tips to prevent WordPress errors:

• Regularly Update WordPress and Plugins: Keep WordPress and plugins up-to-date to ensure you have the latest security patches and features.
• Use a Reliable Web Host: Choose a reliable web host that provides adequate resources and support.
