If I click on System I can then see categories and work my way to my course.
The legacy course file are from the LH menu remained correct in all courses.
No errors were reported during the upgrade I tried accessing from different browsers. I also tried the upgrade on two different servers.
I have restored the server back to 2.1.2 and all is working properly again i.e I can see the course files area from the file picker.
Any help appreciated.
I've just done a quick search in the Moodle Tracker and can't find a report of the problem you describe. Thus, please could you create an issue for it then post the issue number in this discussion thread, so that others can watch, comment or vote for it to be fixed.
I have had the same thing occure in a 1.9.14 to 2.2 upgrade on a linux platform. I also do not have any import screen available with tabs or radio buttons to import by. All I get is a white screen with the first click on the import link. Sounds like backing up to 2.1 is the best thing to do here.
I have voted for the tracker issue. As admin I see the Legacy site files in the Legacy course files repository, while as a teacher I see nothing in the Legacy course files repository.
I will also vote within the tracker. Though, I was logged in as admin and could not view the LCF's when trying to add a file etc. Works just now with applying the patches found within the tracker.
