Yes, we are running both plugins at 3.12
I don’t remember any customizations except for a change to the list widget to correct some spacing issues.
I checked the directory and I’m pretty sure we’ve just been running pro as is since we got it. I think the NEXT events button and issue with the previous event being old are maybe new with an update since March 2015. I can’t be certain when the problem started, but I don’t recall these issues being there in spring or early summer for sure. Thanks.
