Hi, we are experiencing a problem and can't figure out how to fix it.

When trying to access the server with a web browser, we get this error page.

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

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

We went through the Apache logs and found these.
