500 Internal Server Error
The server encountered an internal error and was unable to complete your request.
If this is your Web site and you are seeing this message while trying to run a script, your script probably has a technical problem. See our script support pages for more information.
If you aren't using a script, or you're sure your script file is okay, another possibility is that you have created a custom ".htaccess" file that contains syntax errors. You can see if this is the problem by temporarily removing any custom ".htaccess" file you have created or installed.
You can find more technical details about the error in the error log for your site.
