trouble with new install not getting past "500 Internal Server Error error was encountered while trying to use an ErrorDocument "

I’m not a noob but not a pro either. I just unzipped files to a CentOS 6 + cPanel server. I tried changing the ownership and permissions several times but still getting the following

Internal Server Error

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

Please contact the server administrator at webmaster to inform them of the time this error occurred, and the actions you performed just before this 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.

Any help would be appreciated.
