Ultimate Guide to WordPress Errors Fix: Common Issues Solved

WordPress Errors Fix is a crucial skill set for any business owner, eCommerce professional, marketer, entrepreneur or founder who relies on this powerful platform. With its extensive capabilities and customizability comes the potential for various issues to arise. In this comprehensive guide, we’ll cover a range of solutions to the most common WordPress errors.

WordPress is an incredibly powerful platform, but it’s not immune to technical issues. Dealing with these errors can be frustrating and time-consuming. Thankfully, most of these glitches are fixable without professional help. By familiarizing yourself with the most common WordPress errors and their causes, you’ll be able to troubleshoot your site more effectively. In this article, we’ll provide some helpful tips for resolving WordPress errors on your own. Then we’ll explore 20 of the most prevalent problems users encounter and offer solutions for each one. Let’s get started!

Getting started with WordPress error troubleshooting

When encountering an error on your WordPress site, it can be challenging to pinpoint the cause. However, there are some general troubleshooting strategies you can use to try and resolve the issue. One of these strategies is clearing your cache. Your browser’s cache stores data that helps load sites faster, but outdated content may cause problems. Clearing this cache could solve the problem. Updating your theme, plugins, and WordPress core is also worth considering. If a new plugin or theme caused the error, deactivating it might fix things. It’s always a good idea to keep regular backups of your site in case of irreparable damage from an error. These backups will allow you to restore previous versions of your page without losing critical information.

How to fix the common WordPress errors

Here’s our guide to solving 20 common WordPress errors.

1. The white screen of death

The white screen of death is a term used to describe a completely blank and unresponsive screen. Sometimes, it may display an error message indicating the problem. The main reasons behind this issue are usually related to plugins or themes that cause compatibility issues leading to site inaccessibility. Nevertheless, there could be other factors responsible for this problem as well.

2. 400 errors

400 errors are a type of HTTP client error that can manifest in various forms, ranging from 400 to 499. These errors typically arise due to communication issues with the server and can cause inconvenience for users trying to access a website or web application. Each specific client error code requires a different solution. For instance, resolving the 401 unauthorized error or the 403 forbidden error may involve implementing one of several potential fixes. Additionally, we have put together a comprehensive guide to assist you in addressing the frequently encountered problem of the 404 not found error.

3. Internal server error

Encountering a 500 error can be quite confusing as it doesn’t provide much information other than indicating that your server has crashed. Therefore, resolving an internal server error usually involves some troubleshooting efforts to identify the root cause of the problem. Nevertheless, there are specific steps you can take to rectify this issue and get your website back up and running smoothly.

4. Memory limit error

If you encounter a memory limit error, it could be due to the amount of server memory allocated by your hosting provider. Your plan usually comes with a specific limit, and exceeding it will result in this error message. To resolve this issue promptly, you can increase your PHP memory limit as outlined in step six of our guide on fixing HTTP image upload errors. However, if you frequently experience this problem, upgrading your hosting package may be necessary.

5. Error establishing database connection

When your WordPress site fails to connect with the MySQL database, you’ll encounter an error message that prevents users from accessing your content and restricts your access to the dashboard. However, resolving this issue is not difficult. Begin by verifying that your database credentials are accurate. If they are correct, attempt these solutions to rectify the problem with connecting to the database.

6. Exceeded maximum upload file size

To upload files to your WordPress site, you need to be aware of the maximum upload limit that is set by default. This limit depends on various factors and if you try to exceed it, an error message will appear. You can check your current limit by going to Media → Add New. If you want to increase your upload size, one way is to modify the php.ini file. However, not all hosting plans support this method so it’s best to consult with your hosting provider first or consider compressing your images instead.

7. Maximum execution time exceeded

To prevent your site from timing out and failing to complete a data processing task, it’s important to set a maximum execution time limit. However, if the processing takes longer than this limit, the task will still fail. To solve this problem in WordPress.org, you can add some code to your php.ini file, which is quite simple.

 max_execution_time = 60
While the solution above could effectively resolve the problem, it may not always yield positive results. As such, reaching out to your web hosting provider might be a more viable option for addressing this issue.

8. Failed auto-upgrade

Updating your WordPress site automatically can be a convenient way to stay up-to-date with the latest technology without any manual intervention. However, sometimes this process may not work as expected, resulting in a website crash. In such cases, it is recommended to manually update your site while taking necessary precautions to ensure that the upgrade process goes smoothly and safely.

9. Failed to write file to disk

If you attempt to upload media files, you may encounter the error message “Upload: Failed to write file to disk”. This can be particularly frustrating if your website relies heavily on images.

Generally, there are two main causes:

  • Incorrect file permissions.
  • A server error.

One possible way to address the issue is by verifying that your file permissions are configured correctly. If this approach doesn’t yield any results, you may want to reach out to your hosting provider for further assistance.

10. Connection timed out

When running a website, it’s common to encounter server limits that can result in connection timeout errors. This is particularly prevalent for shared hosting plans. To address this issue, you can try deactivating all plugins and then reactivating them one by one until you identify the resource-intensive program causing the problem. Switching to a default WordPress theme may help, although high-quality themes typically don’t cause such issues. Finally, consider increasing your memory limit as another potential solution.

11. Secure connection error

If you encounter a secure connection error while trying to update your WordPress core files, it means that there is an issue with the server configuration. This problem prevents your website from connecting to WordPress.org and can be frustrating. Although there are no DIY solutions for this error, waiting for a few minutes may resolve it automatically. If not, contacting your hosting provider directly is recommended.

12. Stuck in maintenance mode

Maintaining the security of your site requires updating its core software from time to time. During such updates, WordPress creates a .maintenance file which is typically removed after completion. However, there are instances where this process fails and your site gets stuck in maintenance mode. Thankfully, resolving this issue is quite easy. You just need to connect to your site’s server using an FTP client and find the .maintenance file in the root folder before deleting it. Once you’ve done that, your website should be back up and running normally again without any issues.

13. Cloudflare error 521

Encountering a 521 error on your website can be frustrating. This error is usually caused by Cloudflare’s inability to establish a connection with your server. Fortunately, there are several steps you can take to resolve this issue. Firstly, ensure that your server is functioning correctly and available for access. Secondly, check if any firewall settings or security protocols are blocking Cloudflare’s IP ranges from connecting to your server. If you’re unsure how to do this, contact your hosting provider for assistance in troubleshooting the problem.

14. Images aren’t working

At times, WordPress may encounter issues displaying images, resulting in broken media files as seen in the media library. The causes of this problem can vary from malicious activities to server errors. If you have recently installed or updated a plugin, it’s advisable to deactivate it and check if that resolves the issue. Another possible cause of image display failure is incorrect file permissions. In such cases, adjusting your uploads permission to 755 might help resolve the problem. However, if this solution fails to work for you, we recommend conducting a security scan and reaching out to your hosting provider for further assistance.

15. File type or page access not permitted

WordPress restricts certain file types from being uploaded to your site due to security concerns. This measure is in place to prevent any unauthorized access or hacking attempts on your website. However, this can sometimes limit users from uploading harmless files. To enable the upload of additional file types, you can make use of a free plugin like File Upload Types.

16. WordPress syntax errors

Syntax errors are caused by issues with the structure of your code. These errors usually don’t occur on their own, but rather in specific situations. There are two common scenarios where syntax errors may arise:

  • If you have recently introduced some personalized code to your website and it contains a syntax error, such as a typo that slipped through, then this could be the reason why your site is not functioning properly.
  • A syntax error was caused by the installation of a new plugin or theme.

When encountering a syntax error in WordPress, the error message usually indicates the specific file and line where the issue is occurring. This information can be used to troubleshoot and resolve the problem. If you are unable to identify the cause of the error, it may be helpful to undo any recent changes or installations of themes/plugins. Enabling debug mode in WordPress can also assist with identifying and resolving syntax errors.

17. SSL errors

If you want to ensure your website’s security, obtaining an SSL certificate is a smart move. Many reputable web hosts even provide them at no cost. Nevertheless, the process of setting up a certificate can be intricate and may lead to various WordPress errors. To prevent encountering these issues, it’s crucial to install your certificate accurately from the start. One way to do this is by utilizing your hosting provider’s SSL installer tool, which is often available. Additionally, you should:

  • Ensure that your WordPress website is correctly set up to utilize HTTPS..
  • It is important to ensure that your SSL certificate is renewed on time, especially if your hosting provider does not handle it. 

Contact customer service if you still have issues with your host’s SSL certificate.

18. Corrupted database

When a file becomes corrupt, it can cause issues for your WordPress site such as the “Error Establishing Database Connection” error. To fix this problem, you can restore a backup of your website which should resolve any glitches caused by the corrupted file. Alternatively, you could modify your wp-config.php file by adding specific code at the end to address the issue.


Once you add this code to your WordPress site, it should fix any issues and restore your website to its normal state.

19. Destination folder already exists

Encountering a “Destination folder already exists” error is common when trying to install a plugin or theme. This error message indicates that the program you are attempting to install has been previously installed on your website, and even if you have deleted it, its folder may still exist and cause installation errors. To fix this issue, use an FTP client to access your wp-content directory. Locate the folder with the same name as the program causing problems, delete it, and try installing again. It’s worth noting that in recent WordPress versions, there is an option to reinstall themes or plugins even if they already exist. Therefore, this problem usually occurs only in older WordPress versions (in which case updating is recommended).

20. Locked out of your admin page

Experiencing the inconvenience of being locked out from your WordPress admin page can be quite frustrating as it limits your ability to manage your website effectively. This error, however, has multiple possible causes that range from a simple mistake in password entry to a more complicated issue with the .htaccess file. Nevertheless, resolving this problem doesn’t have to be difficult if you follow our comprehensive guide for troubleshooting. Additionally, you may also attempt to manually modify your admin password or generate a new admin user using phpMyAdmin.
