Hello guys,
I have recently moved complete site which was build using php,cgi and pl files. After migrating the files i am getting this error.

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

Please contact the server administrator, webmaster@xanam.co.uk 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 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

I have tried setting executing permission but still don't work.

Your help on this would be much appreciated.
Many thanks in advance.
