messed up my path in the admin and now I can't access site.

There were 2 fields to change path and I inserted "blog" after a "/" in one of them (can't remember which one). I can no longer access the site and don't know where to take that "blog"out.

I now get redirect to:

http://fitorfad.com//wp-signup.php?new=fitorfad.com

Any clues would be appreciated.
