I have pligg installed on a local system.
MySQL 4.1 + PHP 5.2 + IIS

I installed Pligg without any hitches. The next step was to log into the admin area using the default username and password (god and 12345). So I click the "admin area" button to log in for the first time. On clicking this link it takes me to the login console. (please note the current url at this stage is http://localhost/pligg/admin_config.php). when I log in it display my directory listing (My pligg folder structure).

I cant understand what is happening. The url on my address bar remains unchanged (http://localhost/pligg/admin_config.php). If I click on any of the links such as (admin_categories.php) it takes me back to the log in console. When I re-login it takes me back to the listing.

It is displaying no errors.

Please any help no matter how little will be really appreciated.
