500 internal server error

[abnercc]

I have this screen...help!

The server encountered an unexpected condition which prevented it from fulfilling the request.
The script had an error or it did not produce any output. If there was an error, you should be able to see it in the error log.

What does your error_log file say?

In addition to Corey, please provide more information about your system etc. as well.

It's not easy to come with solutions based on only an error message.
