MyBB Community Forums

When i am installing the forums, everything goes okay.. it rights everything to the database etc, but when it shows the last pages, it says there is an error in a line in the install/index.php

I removed the install files and when i went to my forum, instead of the links in the forum being
- ....com/forum/index.php
they would show up as
- ....com/index.php

I made sure everything was installed correctly inside the forums directory.

Any of you know what is the problem?

Admin CP --> Settings --> General Configuration --> Board URL - make sure it's set right.
