gerikg, I found your site and looked at a sample page. The href of the “log in” link is as follows:

http://kiaspeed2.com/forum/bb-post.php" enctype="multipart/form-data" hack="bb-login.php

It should just be this:

http://kiaspeed2.com/forum/bb-login.php

The text of this href comes from function post_forum inside /bb-includes/template-functions.php. Did you do a core hack of this function? If so, reversing it should fix your problem. Otherwise, one of your plugins has screwed up this function and it needs to be disabled…
