So I installed both #hubzilla and #zap on my #Yunohost server. For some reason I can't post in Zap (my post just disappears when I post it) and I can't connect outside my channel. Hubzilla works fine for both.
Not sure whether this would be a Yunohost, or Zap issue. 🤔
Ok, when I installed #zap this time, there was the option to choose PostgreSQL as the database, so I tried that because, well, just 'cause I guess.
After I found posting wasn't working, I tried uninstalling Zap and reinstalling it with MySQL this time, and that seems to have resolved the problem.
I haven't dug into what caused the problem. I'm just happy to have it working!
