I've been trying to figure out this error that keeps coming up on my SP2010 Foundation server event viewer:
Error loading and running event receiver TaskAlert.Assigner in TaskAlert, Version=18.104.22.168, Culture=neutral,PublicKeyToken=8c9fc716f38d08b2 . Additional information is below. : Object reference not set to an instance of an object.
I currently have 3 sites but 1 site is causing this anytime an item is created on a list.
I've tried repairing the SP install, patching to the latest CU, and cleared my config cache but it is still doing it and it has SP2. This has to be something site related since the other 2 sites with the same workflow does not cause this error but I am lost.
