I can't login to the admin because it's stuck in the "finish upgrade" screen.

I can get into phpmyadmin though, so if there's something I can do in there, any suggestions?

In phpMyAdmin, look in the xf_option_group_relation table for any rows with an option_id of "boardUrl". Remove them and then retry the upgrade.

Thank you Mike.
