In order to resolve this problem, you will need a systematic approach. Following are some other minor issues that can be the reasons for this error. 

Server Misconfiguration: An incorrectly configured server may be the cause of the HTTP 500 error. This could involve problems with server modules, or incorrectly configured server software (such as Apache or Nginx).

Programming Error: Web programs or scripts with bugs in their code can cause the HTTP 500 error. This covers logical, runtime, and syntactic issues that result in unexpected application failures.

File & Directory Permission: The HTTP 500 error might occur when the server cannot access or execute specific files due to incorrect file and directory permissions. Making sure that directories and files have the appropriate permissions set is crucial.

Simple Solutions for the HTTP 500 Internal Server Error 

Here are some really easy solutions by implementing which you can easily fix the HTTP 500 Internal Server Error. From simply clearing your browser cache to fixing the corrupted .htaccess files, we have mentioned all the solutions for some major issues that can cause this error. 

1. Get the Browser Cache Clear

The very first step that you can perform, when you face this HTTP 500 internal server error in your website, is clearing the browser cache. This is a quick fix to this error, just clearing out the cookies and cache. Moreover, this step can also help you t fix the 404 server error, as well. This quick fix is because sometimes cache files can get corrupted, and prevent you from accessing your desired website. 

Before you clear your browser cache, check out if your website is down for anyone. For this you can go to the website “Is it down right now”, and check the status. If the error is showing only on your screen then it can be most probably a browser cache issue. Clearing the cache and cookies method is different for every browser. You can do this step simply by going to your browser settings. 

2. Don’t Forget to Backup Your Site

It's a good idea to create a backup of your website, especially if you're dealing with issues like the HTTP 500 Internal Server Error. Before making any significant changes or attempting corrections, you must have a recent backup of the files and database on your website so you can ensure that, in the unlikely event that something goes wrong, you can restore it to a stable state.

There are multiple ways to back up your website, depending on how it's configured. If you use a content management system (CMS) like WordPress, you may utilize plugins to automate the backup process so that you can create regular backups and securely store them on your server or in the cloud. Your website could be brought down by a simple coding error. You have two options to back up your WP site: manually or using reliable WordPress backup plugins.

3. Clear Your WordPress Cache

The next possible thing is that your WordPress website has a 500 internal server issue, thus preventing the site from loading correctly. If your cache is holding an old version of your website, you may continue to experience problems even after fixing this error. To ensure that you and your visitors can see the most recent version of your website, you must ensure that your WordPress cache is cleared. 


Here are some steps mentioned to clear your WordPress Caching Plugins Cache:

  • Enter the WordPress Dashboard and log in.
  • After installing, turn on the Breeze plugin.
  • Proceed to the Settings area of the Breeze plugin.
  • Mark the choices you want to use in the Settings section.
  • The webpage will be reloaded after the cache is cleared. 

4. Always Check for .htaccess File

The setting of your website is managed by a crucial file found in all PHP-based applications: the .htaccess file. A 500 internal server error may occur if your .htaccess file is corrupted. This file is typically impacted by an improperly installed theme or module. Here is how you can access and modify these files as it is a potential solution for this issue. 

  • From your website's root directory, open the .htaccess file.
  • Make a backup of the file to ensure you can undo modifications if needed.
  • Edit the file with a text editor and check it for errors.
  • Check that the rewrite rules for URL redirection have the correct syntax.
  • To denote that the code is dubious, use a # symbol.
  • Once the file has been edited, submit it and visit your website.
  • If the restore doesn't work, restore the original file from the backup.
  • Ask a developer or your hosting provider for assistance if you need it.

If you do not have access to the cPanel, you can simply install “File Manager Plugin“, and can easily access .htaccess files. 

5. Do the Plugins & Theme Audit

Another thing you can do is make sure your website is using the latest recent plugins by doing regular plugin audits. Incompatible or out-of-date plugins can result in errors on your WordPress website due to compatibility problems. You can follow these simple steps for manual auditing. 

  • Access your WordPress dashboard.
  • Make a note of the plugins you wish to disable.
  • Select Deactivate from the drop-down menu by clicking on it.
  • Refresh your website. 

Even with the greatest WordPress themes, there are situations when they can cause a 500 internal server error. However, you can follow these mentioned steps to perform theme auditing and fix this issue. 

  • Access your WordPress dashboard.
  • Select Themes under Appearance.
  • Turn on the theme Twenty Twenty-Four.
  • When a new theme is activated, your old theme will be instantly deactivated.

6. Increase PHP Memory Limit

PHP workers begin to accumulate a queue when they are already overworked on a site. The queue begins to push out older requests once you've used up all of your PHP workers, which may lead to 500 errors or incomplete requests. Changing the code in any of the following files is one of the most popular methods for raising the PHP RAM limit for a WordPress website.

  • Adjust the Function.php file OR you can go to “.htaccess files” from the “File Manager” Plugin
  • Edit your .htaccess file
  • Tweak the WP-config.php file 
  • Customize the php.ini file for advanced settings

7. Fresh wp-admin And wp-includes

With third-party themes and plugins, a typical WordPress website is difficult to audit its source code. If none of the above solutions work, you can try this one as a last resort. All of your data will be lost, though, so keep that in mind. It is therefore advised to back up your website before doing this procedure. The new wp-admin and wp-content directories must be downloaded and uploaded over FTP to the live host. 

  • Go to the WordPress.org homepage.
  • Select "Get WordPress."
  • Click "WordPress 6.4.3" to get it.
  • With this, the most recent version of WordPress will begin to download.
  • Take out the.zip file.
  • Use an FTP client to connect to your WordPress website.
  • Locate the wp-admin and wp-includes files by going to the root folder.
  • From the extracted files, pick the wp-admin and wp-content files, then drop them into the FTP client window.
  • Choose overwrite and make sure to use this operation consistently.
  • To proceed, click OK.

To Curl Up!

After completely understanding this HTTP 500 Internal Server Error, its causes, and the solutions, you can now easily fix this issue, for sure. These are very simple solutions to fix this problem that web developers usually face on their website. Any of these solutions can work, you just need to give them a try. Moreover, this will not require more than 15-20 minutes and you have your website in perfect condition and visuals, again.
