deleting a custom field redirects to wrong page

Upon deleting my created fields, I got an error. My multi-domain ubercart powered drupal 6 install is currently installed to www.example.com/dev/drupal and upon installing one of the fields, I get redirected to a confirmation screen "Are you sure you want to delete....", when I confirm, I'm redirected to this page:

http://example.com/dev/drupal//dev/drupal/admin/store/settings/checkout/...

As you can see, /dev/drupal is there twice.

I will completely remove the module now and see what happens. Thanks for any assistance blackice78!
