That divide by zero error sounds much like last PTR so hopefully it'll be fixed soon, like last time, there was no problem with Censusplus by the time it went live, even though it'd been crashing with that error on PTR.
I heard from Rollie today btw; he's been totally tied up in RL the last few weeks (not sure if it's fair of me to share what he told me, but it's definitely a good reason; he's been having a bad time of it), but he does intend to try and get caught up on things very soon. Hopefully he can look over the forum and respond to a few queries at the same time!
