These are not the droids you're looking for.
The 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.
Most of the time, "gone wrong" means an issue with the page or site's programming, nothing you have anything to do with.
Note: More specific information about the cause of a particular HTTP 500 error is often provided when it occurs on a server using Microsoft IIS software. Look for numbers after 500 as in HTTP Error 500.19 - Internal Server Error which means Configuration data is invalid.
