Missing +People within Course for site admin user

[brandonfranzke]

Summary:

Identical issue: https://github.com/instructure/canvas-lms/issues/2128 (see figure for my exact issue):

Using master account to view People page, the "+People" button has gone. No errors show in control panel of google chrome. Tried to add a teacher into the course, cannot see it, too.

Posted a follow-up since OP marked resolved but no response.

Additional notes:

I attempted a new postgres DB with a "fresh" environment (rake db:initial_setup). I create a dummy course and check with admin user and can see the "+People". I flushall redis, update database.yml, and restart the server and the "+People" button disappears. I assume it is related to some permission check that is failing. I dont know if its helps but during debug I log every call to "can_do" helper. For the "fresh" install with admin viewing Course > People is see:

after swapping db, flushing cache, and restarting I see only:

canvas-web  | [19988d0bdc988193f2c6f79b780464e3 564da12d-8f08-40fe-bbed-1476bff7259c] can_do, , 1, [:create]

So it seems that there are some conditionals to get to :manage_students check that are not happening. This would explain the missing HTML elements, but I have not been able to track down on server side.

Aside: Any chance this is related to "granular" permissions feature? The break was sudden but unnoticed for several weeks (presumed) and those were the last option I recall adjusting.

I had the exact same problem, plus I was unable to see the people inside a course, kept getting an error message. Changing the People Page Upgrade option in Settings > Feature Options solved it for me.

[brandonfranzke]

Fantastic!! Solved.

@brandonfranzke Was this feature flag turned on for you or it was off?

[brandonfranzke]

It was turned ON. I turned off, flushed redis cache / restarted container and all UI elements show. (not sure if latter was required, but non-destructive).

[omarpr]

Sounds good. Thanks for the info!
