Thread:Extension talk:WPMW/Special:SpecialPages stops working with AuthWP and MW 1.20.3/reply (5)

I have two pretty much identical MW(1.21.5) + WP (3.9.1) setups where this is set up. Another one works just fine but another gives empty SpecialPages IF I have BuddyPress activated. Debugging this more in coming days, wish me luck!
