"Data base errors" in "subscriptions" after forum update

After forum update I get “Database error” message after clicking on “Subscriptions” in Inbox.

Hey BoredEngineer,

Can you copy/paste the full error message here? I had one earlier and we’ve since fixed it, so I’d like to make sure this is fixed as well or if it’s not fixed, I’ll need more information.

Thanks! Sorry about the error.

Can’t do that anymore - error is gone and everything is working.
Will screenshot it next time.

Ok, if it comes back, just let me know and I’ll get it fixed ASAP.
