Error when setting up self host

I am trying to set this up on my webpage and I get an error whenever I try to set it up. The database tests successfully however when i continue it creates the databases and then errors out. Here is the error message.

Internal Server Error

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

Please contact the server administrator, webmaster@********.com 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.

Are there any more details in the web server error log?

A common cause for this sort of error is permission issues.

Because of the nature of my webhost account i am unable to run chown commands, is there a way to work around this and is this causing my issue?

If your server supports FTP access you may be able to use an FTP client to do it.
