Thanks Varun. I actually needed to go back further than that, but I was able to figure it out. Why don’t they put an index in there? I had to type several version numbers before I got one that actually existed.
In case you’re curious, I got all excited when I discovered BP Groups Hierarchy, until I realized it doesn’t work. Apparently, it did at one time, but it started developing problems with BuddyPress 5.0, and hasn’t been updated since.
I was thinking of trying to fix it, but now I’m thinking it might be easier to just start from scratch. Instead of trying to make the groups hierarchical, I used the Pods plugin to build a tree, each node of which will have it’s own group.
