Tasks, Events & Settings not working anymore

Tasks, Events & Settings not working anymore

Dear all,

since almost an hour ago our Connect lost most of its functionality. All of the pages now have "undefined" as the meta tile and the followoing functions don't work anymore:
  1. All the tasks are gone. Task boards are still there though.
  2. All the events are gone.
  3. The navigation on the right side (options, users, integrations) is not working at all.
Is there any way to fix this? Did any of you encounter this problem before?
