Originally from MDL-68459 (now split from it), we need to check (and fix if needed) why this is being reported in logs:

Problem C: Course or activity not accessible (maybe it's ok). It happens 3 times.

It happens with scenarios: "Do not restore a draft if files have been modified", "Do not restore a draft if text has been modified" and "Content viewed event".

The first 2 cases are with the autosave ajax script being not logged in on course edit page. The 3rd with report loglive ajax returning the same. Maybe a pause is needed or something to allow those ajax scripts to know they are logged in.

Originally from MDL-72815 (now split from it), the very same error is now happening in different scenario, not in the original ones, it seems:

Problem D: Default exception handler: Course or activity not accessible. It happens 2 times

Maybe caused by previous problem (same request)!

Happens in scenario: (not always!) --tags '@mod_data' --name 'View automatic completion items as a failing student'
