tom23 it's because of FreeFlarum upgrading all forums to Flarum v1.3.0, which I've announced here. If your forum is still unaccessible, please tell me its name and I will sync it for you.
jaypatelani AFAIK no extensions should be disabled automatically after an upgrade both from Flarum and FreeFlarum's side, so I am not sure what exactly went wrong there. However, I am glad that you hopefully sorted it out, please let me know if you need further assistance
