NTOPNG partially broken

This is strange, my NTOPNG is broken. Actually its been broken for a while, likely since the 2.8.x update. I don't use it all that often.

But here is the really strange part, its working somewhat. I can enter the GUI, but all metrics are missing. The REDIS database looks to be running.

Is there a way to export my settings, delete from PFsense, reinstall and restore settings? I just don't wanna import a possibly corrupted backup file causing the same issue all over again.
