How to Fix the Common WordPress Errors: Causes and Solutions


WordPress, as we all know is one of the popular CMS platforms to build websites. It is easy to use, customizable and entails lots of free themes and wordpress plugin  to set up a business or personal website easily. However, just like anything- no one is perfect, there are a few errors users will run into when using WordPress.

Every WP user encounters common WP problems at least once. Luckily, with supportive, vast user base, and using a reliable host like, these errors can be fixed. In this post, we are going to learn about WordPress errors, their causes and the ways to fix them.

Let’s jump in

WORDPRESS ERROR 1 – Internal Server Issue

One of the most confusing and irritating WP errors is ‘Internal Server Error” or “500 Internal Server Error.’ You will see this error when something is wrong and the server is unable to find out where the major problem lies. Since the error message doesn’t indicate the probable cause, so, it’s all upon you to find out where the problem actually exists.

Causes and Ways to fix it

There are a number of reasons for this issue, and similarly, there are several ways to fix it.

1. Check .htaccess

The .htaccess contains crucial server directives like rewrite rules to enable pretty permalinks. When it gets corrupted, the “Internal Server Error” pops up. So, in order to check if something is wrong with it, access your server through FTP and look for the file in root directory. It is hidden by default, so, you might have to activate “force showing hidden files” to see it.

After you’ve found the error, right click on the file and rename it, for instance- .htaccess_old and try to reload your site. If your issue is fixed, log into your website and save the permalink structure to generate a new .htaccess file.

2. Increase your PHP memory limit

Internal server errors are often caused due to insufficient memory. In such a case, you need to enhance the limit of existing memory inside wp-config.php.

This helps you to increase your memory up to 256 MB, depending on your necessity. If the error is regarding insufficient memory, your problem must be solved.

3. Deactivate all plugins

If the above two solutions didn’t solve the error, then the third way is to deactivate all plugins, as the error may be a result of incompatibility or another plugin problem. After deactivating all the plugins, reactivate them one by one until you’ve found the main error. In case you don’t have access to the admin area, deactivate the plugins by renaming the plugin folder in wp-content through FTP.

4. Re-download the core files of WordPress

Another common reason is – your core files have been corrupted. To fix it, download the latest version of WordPress and replace the wp-includes and wp-admin folder to your existing installation with the newly downloaded ones. You won’t lose any content but can fix your problem.

5. Have words with your host 

If none of the above ways fix your problem, there are chances that something’s wrong with the server. So now, the only solution left is to talk to your host to fix the error from their side.

WORDPRESS ERROR 2 – Error in establishing a database connection

This is another common error you may come across while using WordPress. A database is a place where WordPress secures all your content such as pages, posts and other important information. It is the most important part or we can say the soul of your site without which your site will not exist. So, when the database connection is down, your site becomes slow.

Causes and Ways to fix it

Most of the time, this error is caused due to some wrong credentials within wp-config.php. But, there are other reasons as well.

1. Wp-config.php

This file entails all the login information for the database such as username, password, server etc. You can look for it in the root directory of your WP installation. In case of any issue, make sure to check the credentials precisely.

2. Access wp-admin

When the above solution didn’t solve your issue, it’s time to look into a database that causes the need of WP to fix it. In such scenarios, go to your WordPress website’s admin panel (

Allow Repair

There, you will see a weird kind of error message stating your database needs repair. When you see it, your next step is to add the line- wp0-config.php in order to activate this feature.

The next step is to access to start the process. When you have completed it, make sure to remove the line from wp-config.php to restrict other people to have access to this function.

3. Communicate with your host

A reliable host like can help you solve your problems if the above two solutions don’t work. As the problem might be lying on the host’s side and there is something wrong with your MySQL server. You may also have reached or surpassed your allocated database server limit. In both of these cases, only your host can provide you the right solution.

WORDPRESS ERROR 3 – White Screen of Death

What the blue screen of death is for Windows users, the White screen of death is for WordPress users. It indicates that your site is out of track and browsers have nothing to show. It can affect your site negatively. The most problematic part of this issue is that you will not receive any error message related to this issue. So, you have to try many things prior to it and find the real cause of the error.

Causes and ways to fix it

Fixing a white screen of death requires you to

1. Increase the memory limit

This problem usually arises because of memory issues. Therefore, you have to fix it by increasing the existing memory size.

2. Disable all WP plugins

If you think that there is some problem with the plugin, just disable them and find out which one is causing the said problem.

3. Use a default theme

If there is some fault in your theme, it can cause a problem. So, it’s better to use a default WordPress theme. In case you don’t have access to WP backend, you can make relevant changes via FTP. For that, just go to the theme folder and rename your existing theme folder. This enables you to make WP get back to its default theme.

4. Activate debug mode

If neither of above solution works, put WP into debug mode with the line of code in wp-congig.php. From false, switch it to true and update the file over your server and start debugging.

Activate Debug Mode

This helps in output errors, outpit warnings and notices on a page that will aid to filter the main issue.
