Thread:Extension talk:UserFunctions/Stopped working with MW 1.20.2

Hi.

I've just upgraded a MW 1.19.3 instance to 1.20.2 and all my #ifsysop and #ifingroup functions have stopped working. They just display {{#ifsysop: instead of being parsed. All works fine with 1.19.3. I have $wgUFAllowedNamespaces[NS_MAIN] = true;

I guess, once again, MW has changed something vital between 1.19.3 and 1.20.2 that has broken this.

Any ideas? Thanks
