Chatsong_ It seems that it got deleted when we were cleaning up inactive ones, but it's not necessarily gone forever - I just need the URL to know what to look for
JeloLeaks Fixed after clearing the cache.
It seems that when you enable PWA, the forum crashes. I will update all extensions and sync all forums to see if it helps. Since it resolves after cache clear, I don't think that it's actually an issue. Cache is supposed to be cleared sometimes. I will implement a system to do so from the FreeFlarum settings directly, if your forum breaks again.
Also everyone, when you are requesting support please always include your forum URL. We don't know what forum you own or what went wrong otherwise. Thank you
