Notification Flag Icon Error

• Firefox Ver 58.0.2 (64-bit)
• OSX El Capitan Ver 10.11.6
• No Extensions

Today I went up to the flag icon to check my notifications and got an error message when I hover the mouse over the icon. Click on the flag icon also shows me to a 500 error on the notifications page. This happens on any page you can access the notification flag icon.

Here is some console screenshots, but it doesn't look like there's anything obvious.

Might be related to profile page since that is also showing the 500 error.

Yep, it looks like notifications are acting pretty funky right now. I've let the engineers know; hopefully someone can do something before they all go home.
