How to Fix 500 Internal Server Error in WordPress?

In WordPress, are you getting a 500 internal server error? One of the most common WordPress issues is the internal server error. Since the error doesn’t give any other information, many beginners find it quite frustrating. We’ll teach you how to resolve an internal server problem in WordPress in this post.

Internal server issue is not just for WordPress. It may happen to any website that is hosted on a web server. Due to the generic nature of this error, it does not tell the developer anything.

Asking your doctor how to fix an internal server error without telling them where the pain is is like asking them how to fix a pain without telling them where the pain is.

Plugin or theme functionality often causes internal server errors in WordPress. Internal server error in WordPress can be caused by a corrupted. htaccess file or a PHP memory limit, as according to our knowledge.

Internal server errors have also been reported to appear just when trying to enter the admin part of a website, while the rest of the site works well.

With that out of the picture, let’s look at how to troubleshoot the internal server error in WordPress.

When troubleshooting the internal server problem in WordPress, the first thing you should do is look for a corrupted .htaccess file.

Rename your main .htaccess file to something like .htaccess old to do this. To rename the .htaccess file, go to your hosting account’s cPanel dashboard and log in with FTP or the File Manager app.

The .htaccess file will be located in the same directory as the wp-content, wp-admin, and wp-includes files when you’ve connected.

After you’ve renamed the .htaccess file, visit your site to see if the problem has been resolved. If it did, give yourself a pat on the back for resolving the internal server problem.

Before you do anything else, make sure you go to the WordPress admin area’s Settings » Permalinks page and hit the save button without making any changes. This will create a new .htaccess file for you with proper rewrite rules that prevent 404 errors on your post pages.

If the solution of checking for a corrupt .htaccess file does not work for you, you must continue reading this article.

If your PHP memory limit is reached, an internal server error can occur. To fix this, see our tutorial on how to increase the PHP memory limit in WordPress.

If the internal server problem appears just when you try to login to your WordPress admin or upload an image in your wp-admin, you should raise the RAM limit by taking these steps:

1. Create a blank text file called php.ini
2. Paste this code in there: memory=64MB
3. Save the file
4. Upload it into your /wp-admin/ folder using FTP

Several users have reported that completing the steps above resolved the admin side issue for them.

If raising the Memory limit solved the problem for you, it was simply a temporary problem. You must still determine what is causing your Memory limit to be exceeded.

It might be a theme function or a badly coded plugin. We strongly advise you to request that your WordPress web hosting company review the server logs to help you in determining the precise diagnoses.

If increasing the PHP memory limit does not resolve the problem, you will need to conduct more troubleshooting.

If none of the above options worked, the issue is very definitely due to a specific plugin. It is also possible that it is a combination of plugins that are not playing nice with each other.

Sadly, there is no simple way to find out. You must deactivate all WordPress plugins at the same time.

If disabling all plugins fixed the problem, you know it’s one of the plugins that are at fault.

Simply click on ‘Plugins’ in the WordPress admin section. Now you must reactivate every plugin one by one until you find the one that is causing the issue. Remove the plugin and notify the plugin’s author of the issue.

If the plugin option failed to fix the internal server problem, try re-uploading the wp-admin and wp-includes files from a fresh WordPress installation.

This will NOT delete any of your data, but it may help you solve the problem if a file is corrupted.

You must first go to the WordPress.org website and click the Download option.

This will transfer the WordPress zip file to your computer and install it. You first must extract the zip file, which will include a WordPress folder.

The next step is to use an FTP client to connect to your WordPress website. Go to the root folder of your website once you’ve connected. It’s the folder that includes the wp-admin, wp-includes, and wp-content folders.

Open the WordPress folder on your computer in the left column. Select the wp-includes and wp-admin folders now, then right-click and choose ‘Upload’.

These folders will now be sent to your server by your FTP client. You will be asked if you want to overwrite the files. Select ‘Always use this action’ after selecting ‘Overwrite.’

Your FTP client will now replace your old WordPress files with newer, cleaner ones. This step will fix the internal server error if your WordPress files were corrupted.

If all methods fail to fix an internal server error on your website, then it is time to get some more help. Contact your web hosting support staff, who are able to analyze the server logs and identify the error’s origin.

If you want to continue troubleshooting on your own,  We hope this post was helpful in resolving the WordPress internal server error.
