The first thing you need to know about an “Internal Server Error” is that the error can only be resolved by fixes to the Web server software. It is not a client-side problem meaning that the problem is not with your browser, your computer, or your internet connection. However, there are often ways to quickly get around the problem:
Check the Error Logs
Errors in .htaccess files
Clear your browser cookies and cache
Reload or Refresh the Webpage
If you’ve tried to troubleshoot your 500 server error and still can’t fix it, then you may need to speak to your web host and see if they are able to find what process or script is causing the error.
