Since migrating our WPMU site to a new server, we've noticed that ALL new registrations to our WPMU BuddyPress site are being diverted to the page we set the Anti-Splog plugin to divert Spam users to.
When I tried to find and uninstall Anti-Splog from within WordPress Plugins menu, Anti-Splog no longer showed in the list. So, I deleted the plugin's .php file and folder from the mu-plugins folder.
However, the website is still diverting ALL new signups (legitimate or otherwise) to the URL that we'd specified Spam Users to be diverted to.
What is the process for totally disabling and removing the remnants of this plugin so we can get signups working again?
