Just completed an upgrade from 6.5.0 to 6.5.2, and when I went to bring everything back up, certain sections of the board give an "Access denied" error, areas where even guests used to have at least read access. I've reset the permissions to nothing then set them back they way they should be in the control panel and verified that the table w3t_Boards is being changed. But yet the problem still persists, and I'm out of ideas.

Any other suggestions before I revery to backups on 6.5.0 and try the upgrade another day?
