Site name url/ config
 

Hi*

I am finding my system is assigning /forum.php instead of index.php.
My site home address is /index.php however My logo has a link to /forum.php
and when I want to see what style I am useing or to change my style the preview link has /forum.php at end of link thus it get directed to a blank page because I have no / forum.php.

In admin the Site name url/ config is configured to /index.php

please help
Adam
