Thread:Extension talk:WPMW/Special:SpecialPages stops working with AuthWP and MW 1.20.3

I had AuthWP installed on a 1.18.x install and it was working perfectly. I updated to 1.20.x as 1.18.x was going to be deprecated in the near future and now Special:SpecialPages gives me a blank screen when I try to go to it.

Logging in to WordPress and then going over to MediaWiki still works great. The only problem I have is that the Special:SpecialPages does not work.

Thanks!
