500 Internal Server Error Definition and Solution

Various Causes of the 500 Internal Server Error

The 500 internal server error can occur unplanned and cause trouble in loading your website. There can be many reasons for this error to be encountered on the server-side, but if it is your website, then take countermeasures to make sure the website is accessible all the time. Below are some common reasons that your user are facing the error.

  • Permission Error: one of the most common reasons is due to the improper permission for some files required to access the server. This could be the permission to PHP and CGI script that is causing the issue. Changing the user’s permission to 0755 could avoid this problem from occurring repeatedly.
  • PHP Timeout is due to the timeout of the resources required to run required files or scripts. By handling scripts in a better way, you can avoid the situation. 
  • Coding Error in .htaccess File: make sure that the .htaccess file is structured correctly.
  • PHP Memory Limit causes the process to exceed the memory limit and stops the server from responding.
  • Error Logs: check for Apache and PHP error logs, and you will get failure details.

 

Ways to Fix the 500 Internal Server Error

We have discussed some ways to overcome the issue, which may be due to the website’s server. It may be possible that the problem resides from our end, and we can try a few things to make that work.

 

Reloading the Web Page

Try reloading the webpage using the F5 or Ctrl+R option or try pressing on the URL and then Enter. If the 500 error persists after reloading the website again, it might be a temporary issue that would resolve in a few minutes. 

 

Clearing Browser’s Cache

There can be an issue with your cached version of the webpage you are trying to access. Therefore, try clearing the cache for the website to make it work.

 

Deleting Browser’s Cookies

You can avoid 500 server errors by deleting the cookies for the website. Once you delete the cookies, restart your browser to re-access the website.

 

Contacting the Website

If you are unsure how to eliminate this error, you can try contacting the website administrator to look into the error. They might help you in troubleshooting it. If they are also not sure, then try for open-source portals where you can possibly find a solution.

 

Server Timeout

This error may also cause the server timeout or script to get timed out. You can avoid this issue by increasing the Apache server timeout from the http.config file and expand it to 600 for working properly. If the server is busy then, reboot it. In case the connection fails again, you will face the 500 server error once more.

 

Create a Site Backup

For this, make changes to the website’s root directory. It is recommended to back up your site before you make the changes so that you can roll back in case of any further failure.
