Anyone have any ideas why I'd be getting an internal server error on my vB forum?

I went to bed last night with it working fine, woke up this morning to a internal server error message. What is weird is it is hosted as an add-on domain to one of my other sites which is doing fine right now.

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Apache/1.3.39 Server Port 80
