I've had to change the name of the same page a couple times now thanks to an internal resource, which of course caused DNN to puke out a redirect error for the page. I changed "And" to "and" with a lowercase "a" and it went down. I'm unable to access the "more Settings" popup through the page admin due to the same redirect error. The only solution I've seen was to go into the database and remove it from the TabIDUrls or something to that effect. However, I don't have access to edit the database either. I've cleared cache, recycled the domain app and nothing. The site goes to the client on monday, so any help would be greatly appreciated. Thanks... where's the alcohol?

Go to Host > SQL menu.  Run Select * From TabUrls table.  Locate bad record and the run Delele query.
