Hi there -- I'm working on the "Chatter Basics" module (total newbie here) on the "Approving Records from the Feed" trail and keep getting the following error message: 



["There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Process failed. First exception on row 0; first error: NO_APPLICABLE_PROCESS, No applicable approval]

How do I make sure that the Case standard object has Chatter feed tracking turned on? I'm thinking this is the issue...

Thanks for your help! 

And yes I have overriden the compact layout assignment to Phone and Email...any ideas?
