I was able to get to the admin area by removing the “s” in https at the beginning. Then I went to settings and tried to change the bbPress address (URL) from https://www.example.com/forums/ to http://www.example.com/forums/ but it doesn’t save the change. I might have to go in with phpmyadmin…
ipstenu, thanks for your comment.
When I go back to http://www.example.com/forums/ I’m logged in. But when I click on the Admin link, it doesn’t take me there (https://www.example.com/forums/bb-admin/) instead it just reloads the /forums/ page.
Hmm, I think the problem might be related to this plugin which I have installed in wordpress:
http://www.kerrins.co.uk/blog/admin-ssl/
I deactivated it by removing its folder from the plugins folder via FTP. But it didn’t seem to really deactivate. Now I’m trying to activate it so I can deactivate it via the GUI, but it’s not working. I’ll have to investigate it further tonight.
