One of our clients wants to activate the SharePoint Server Publishing features on their environment.
There is no problem with activating the Publishing Infrastructure site collection feature. However it won't be possible to activate the SharePoint Server Publishing site feature in all lms sites, -courses particularly.
This hasn't been yet addressed in SPLMS as of now but most commonly customers ask for this feature in order to propagate custom look and feel to all lms sites. This is currently possible using SPLMS Look and Feel feature and inheriting it in courses from the organization.
