HELLO!!
The wiki's been down for mooooonths, but the recent PHP vulnerability (plus trying to organise my mammoth notes file and finding so many things to add) got me poking at it again, and now it's working. Just needed to fix 2 lines in LocalSettings, whoops 
@gamemakingtools Yay for pushing past inertia! I guess it isn't all bad
@elfi Oh ta! It seems silly in hindsite, searching never turned up answers to the particular error, but a tiny bit of trouble-shooting was all it took.
