Error on newregcomplete

I've been getting this error for a  while now:

Error: Call to undefined method IPS\core\extensions\core\AdminNotifications\NewRegComplete::member() (0)

No idea how to solve it.

You need to disable 3rd party items, then enable one at a time until you find what is causing the issue. That error is being caused by one of your 3rd party items
