Problem with logins from vBa index page

[Chimpie]

Yes, I have already posted this at the vBa forums but no one has responded so I thought I would try here just in case someone has any ideas.

My site: www.skywarnonline.com

When I try to log in from the home page, it returns with a 404, page not found error. This is happening because the url is not including 'forums', as if you were logging in from the forums page. I have multiple sites set up with vBa, with the forum in its own directory. Every other site logs in just fine. I have checked all the settings (I think) I cannot find the difference between them that would cause this error.

Thoughts? Suggestions?

Thanks!
