Top 10 Common WordPress Errors and How to Fix Them Easily

Running a WordPress website means you’ll likely run into some WordPress errors along the way. These errors can be frustrating, but most are fixable if you know what to do. We’ll break down the top 10 most common WordPress errors, what causes them, and the best ways to fix them.

1. White Screen of Death (WSoD)

The White Screen of Death is a major WordPress error where your site shows a completely blank white page with no content or error messages. Visitors see nothing, and site owners often panic because it seems like the entire website has vanished. This error can strike after updating a plugin, theme, or making changes to your code. 

It makes your site inaccessible and can cause confusion and frustration. The White Screen of Death is one of the most common WordPress errors and can occur on both the front end and admin dashboard, leaving you locked out and unable to troubleshoot easily.

This error usually happens due to plugin or theme conflicts, PHP errors, or when WordPress runs out of memory. Sometimes, corrupted files or recent updates can also trigger it.

How to Fix WordPress Errors Like WSoD?

• Disable all plugins by renaming the plugins folder via FTP or file manager.
• Switch to a default WordPress theme like “Twenty Twenty-Four.”
• Increase the PHP memory limit by adding define('WP_MEMORY_LIMIT', '256M'); to wp-config.php.
• Enable debugging in wp-config.php:

php
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

• Clear your browser cache and reload the site.

2. Internal Server Error (500 Error)

The Internal Server Error, also known as the 500 Error, is a general message your site shows when something goes wrong on the server, but it doesn’t specify the exact problem. When this error appears, visitors cannot access your site, and it looks like the entire website is broken or down. This can be alarming and confusing for both visitors and site owners. 

The Internal Server Error is one of the most common WordPress errors and can occur due to a variety of issues, including corrupted files or plugin conflicts.

This error is often caused by a corrupted .htaccess file, plugin or theme conflicts, low PHP memory, or server permission issues. Sometimes, corrupted WordPress core files can also trigger it.

How to Fix WordPress Errors Like 500 Error?

• Rename the .htaccess file and go to WordPress dashboard → Settings → Permalinks, then click “Save Changes” to regenerate it.
• Deactivate all plugins by renaming the plugins folder, then reactivate one by one to identify the culprit.
• Switch to the default WordPress theme to rule out theme issues.
• Increase PHP memory limit if needed.
• Check your server error logs or contact your hosting provider if the problem persists.

3. Error Establishing a Database Connection

This error means WordPress cannot connect to the database where your site’s content, settings, and everything else are stored. When this happens, visitors to your site see a message about connection problems instead of your website loading properly. As a result, your site becomes inaccessible, no pages load, and you cannot even access the WordPress dashboard to make changes. 

This is one of the most common errors and can be caused by a variety of issues, including incorrect database settings or server problems. The main reasons for this problem are usually incorrect database login details in the WordPress settings file, damage or corruption in the database itself, or issues with the database server at the hosting provider.

How to Fix WordPress Errors Like This?

• Verify and correct the database name, username, password, and host in wp-config.php.
• Contact your web hosting provider to check if their database server is down.
• Repair the database by adding define('WP_ALLOW_REPAIR', true); to wp-config.php and visiting yoursite.com/wp-admin/maint/repair.php.
• Restore your site from a backup if corruption is severe.
• Optimize your database regularly to avoid issues.

4. WordPress Login Page Refreshes or Redirects Back

This problem occurs when you try to log in to your WordPress dashboard by entering your username and password, but instead of letting you in, it keeps sending you back to the login screen. This creates a loop, where you are stuck repeatedly on the login page without access to your admin area. It feels like the login process never completes, locking you out of your website’s backend. This is a common WordPress error that can be caused by a variety of issues, including incorrect site URL settings or corrupted browser cookies.

This usually happens because the site URL settings in WordPress are incorrect or mismatched, causing the login process to redirect improperly. Another common cause is corrupted browser cookies and cache, which interfere with the authentication process.

How to Fix WordPress Errors Like This?

• Clear your browser cookies and cache.
• Check WP_HOME and WP_SITEURL values in wp-config.php to make sure they match your site’s URL.
• Rename the .htaccess file and resave the permalink settings.
• Disable plugins that might interfere with login.
• Try logging in from a different browser or device.

5. Connection Timed Out

The "Connection Timed Out" error in WordPress occurs when the website takes too long to load and ultimately stops responding, causing visitors to see a server timeout message or a blank page. It indicates that the server couldn't process the request within the allotted time, often leaving the site temporarily inaccessible and frustrating users who can't access the content or perform actions on the website. This timeout typically happens during periods of high traffic or when the server is overloaded with resource-intensive processes.

The main reasons behind this error are usually that the hosting server is overwhelmed with too many requests or the site is using excessive resources, such as heavy plugins or themes. Additionally, low PHP memory limits can significantly slow down or halt page loading, leading to timeouts.

How to Fix WordPress Errors Like This?

• Increase the PHP memory limit in wp-config.php to at least 256M.
• Deactivate or remove heavy plugins and themes temporarily.
• Optimize your images and database to reduce server load.
• Upgrade your hosting plan or contact your hosting provider.
• Use caching plugins to improve site speed.

6. 404 Page Not Found Errors

When a visitor clicks on a link to a page or post on your WordPress website but sees a “404 Not Found” error instead, it means the website cannot locate the page they are trying to access. This error message indicates that the specific content no longer exists at the requested URL or cannot be found on the server, leading to an interrupted browsing experience for users. This is one of the most common errors and can happen due to broken links, deleted pages, or outdated permalink settings.

This error happens mostly because the links leading to the page are broken or changed, or the permalink settings on the WordPress site are outdated. Sometimes, a page might be deleted or moved without updating the links pointing to it, causing the server to fail in locating the resource and triggering the 404 message.

How to Fix WordPress Errors Like This?

• Go to the WordPress dashboard → Settings → Permalinks and click “Save Changes” to refresh permalinks.
• Check the URL in the browser to ensure it’s correct.
• Recreate missing pages or posts if needed.
• Use redirection plugins to redirect old URLs to new ones.
• Clear your caching plugin or browser cache.

7. White Text or Missing Buttons in Visual Editor

When you are editing posts or pages in WordPress, you might notice that the buttons in the editor toolbar suddenly disappear or the text turns white and becomes invisible. This can make it very difficult to format your content or even see what you are typing. This problem affects the visual editor, where you normally click on buttons for bold, italic, links, and other formatting options, interfering with your ability to create or edit content smoothly. This is a common WordPress error that can be caused by JavaScript conflicts or outdated browser cache.

This issue usually occurs because of conflicts between JavaScript files used by plugins or themes, which can prevent the editor from loading correctly. An outdated browser cache sometimes stores broken or old versions of the editor scripts, causing similar display problems.

How to Fix WordPress Errors Like This?

• Clear the browser cache or open the WordPress editor in incognito mode.
• Disable all plugins and reactivate one by one to identify the culprit.
• Add define('CONCATENATE_SCRIPTS', false); in wp-config.php to prevent JavaScript conflicts.
• Update your browser to the latest version.
• Switch to the default theme and check again.

8. Memory Exhausted Error

The Allowed memory size exhausted error in WordPress appears when the website runs out of the amount of memory it is allowed to use for its operations, causing the site to stop working properly and display an error message. This error can occur during actions like uploading large files, activating heavy plugins, or running resource-intensive themes, especially if the site's memory limits are set too low. This is one of the most common WordPress errors and can be particularly frustrating on shared hosting plans where resources are more restricted.

This problem occurs because WordPress, which relies on PHP, tries to use more memory than the server allocates for it, leading to the website crashing or becoming unresponsive.

How to Fix WordPress Errors Like This?

• Increase PHP memory limit in wp-config.php:

php
define('WP_MEMORY_LIMIT', '256M');

• Contact your host to increase server memory limits if needed.
• Disable unnecessary or heavy plugins and themes.
• Optimize your database and images to reduce memory use.
• Avoid running too many processes simultaneously.

9. Theme and Plugin Compatibility Issues

Sometimes, a plugin or theme on your WordPress website may not work well with other parts of the site, causing crashes, errors, or problems with how your pages look. This means certain features might stop working, or your site may not display properly, making it frustrating to use and confusing for visitors. This is a common WordPress error that can be caused by outdated or poorly coded plugins and themes.

These issues usually happen because the plugins or themes are old or not designed to work with the current version of WordPress you are using. Sometimes, they might also clash with each other, which creates conflicts that break your site’s normal function or appearance.

How to Fix WordPress Errors Like This?

• Keep all plugins and themes updated regularly.
• Switch to the default theme to check for compatibility.
• Deactivate all plugins and activate them one by one.
• Remove unused plugins to reduce conflicts.
• Choose plugins and themes from trusted developers.

10. Image Upload Issues

When you try to upload images to your WordPress website, sometimes the upload fails, or the images appear as broken links on your site. This problem can be frustrating because your content might be ready, but you can’t add the pictures that make your pages look complete. It can happen when you upload directly to posts or through the media library, and it stops your site from displaying images correctly. This is a common WordPress error that can be caused by server settings or plugin conflicts.

This issue usually happens because of incorrect settings on the server that control file permissions or because the server limits resources like memory or upload size. If WordPress does not have permission to write files in the uploads folder or if the server restricts the file size, images won’t upload properly.

How to Fix WordPress Errors Like This?

• Check and set folder permissions: 755 for folders, 644 for files.
• Increase PHP memory limit in wp-config.php.
• Temporarily disable any plugins related to image handling.
• Clear the browser cache and try uploading again.
• Contact the host if the server’s temporary folder is full.

Conclusion

In conclusion, dealing with WordPress errors can be stressful, but most problems have simple solutions if you know what steps to take. Whether it’s a White Screen of Death, a 404 page not found error, or a database connection issue, the key is to stay calm and follow a systematic troubleshooting approach. Always keep your WordPress core, themes, and plugins updated, and regularly back up your site to avoid data loss. Use debug mode in WordPress to get detailed error messages, and don’t hesitate to reach out to your hosting provider if you’re stuck. By following these best practices, you’ll be able to resolve most errors quickly and keep your site running smoothly for your visitors.
