Cause of HTTP 500 ErrorsThe 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the web site's server but the server could not be more specific on what the exact problem is.
That's not a lot of information to go on but there are a few things you can do.
How To Fix the 500 Internal Server ErrorThe 500 Internal Server Error is a server-side error, meaning the problem is not with your computer or Internet connection but instead is a problem with the web site's server.
Even though the issue is not yours to fix, there are some things you can try:
Reload the web page. You can do that by clicking the refresh/reload button, pressing F5, or trying the URL from the address bar again.
Even though the 500 Internal Server Error is reporting a general error on the web site's servers and not your computer, the server error may only be temporary. Trying the page again will often be successful.
