Installed on temporary URL - Admin access broken?

I have installed the template on a temporary URL as we don't want the existing site to suffer any downtime.

The installation of the template (and joomla) seemed to go well, yet when I attempted to login to the administration section, I received an error, which I've attached a screenshot of. The error says "Component Not Found".

The URL is 205.234.140.231/~cathad/index.php

Also, when attempting to go to the root temporary domain, we receive the error which I've attached a screen shot of.

205.234.140.231/~cathad/

Because your base site takes control when there is no index.php at end of url. It can not find /~cathad so it pops you error.

Thanks, Ivan.

What about the error when attempting to login to the administrator page?

same thing. You need to configure root site not to process rquests for /~cathad

Is there an easy way to do this?
