I’ve just set up a bbpress forum and everything seemed to work one day, then the next it stopped. All registrations and new posts would lead to a blank page. I couldn’t find the problem in the code, reinstalled a few times, and eventually I found out it was because of akismet. For some reason, it was flagging new registrations and posts as spam or something. It would leave the page blank, so I never knew what was going on.
I’ve removed the API key from my config.php and everything works fine. My forum is currently unlinked because I’m still setting up. But I would like to get akismet working before the spam hits it
