Deleted punbb files / redirect error

Hello,

I'm keeping my fingers crossed someone can help me with a very specific issue.

For various reasons I deleted PunBB and Wordpress directories from my site http://superviva.com

Now when someone registers or logs in they see a page that is blank except it says:

     Wrong forum/, no punBB files

When you go to the home page it loads and you are logged in or registered, which leads me to believe something is directing the registration to this non-existent place.

Do you know which php file might be doing this?

FYI the site is built with php / mysql.

Thanks so much for any help or direction to other forums if this really isn't a punBB issue.
