Need help with a notification error.

I have a thread on Bugs reporting, but no-one has replied. Can a mod pass the issue on to the dev team? Multiple users - including myself - are having "500: internal server error" messages when looking at the notification icon. It changes colour to signify a notification, but I cant read who's replied to a comment. Been like this for about 10 days now, on mobile and desktop. Tried multiple browsers, and disabled all add ons.

Our GS Staff lead is looking into the issue now and when will it be fix, is anyone's guess.
