We are using PP at http://www.artisticalley.org/gallery/
and have been for years. Last weekend, for no explicable reason, our admin control panel became completely inaccessable; people can still submit art, and post reviews, and view everything, and we can administrate from the site's public pages and even access the "admins only" forums, but we can't get to the Admin control panel at all. If I try to get to said page, it takes me to the login page, and then, nothing.
Is someone able to help us with this?
