I've tried restoring a course and all I get are the topic labels - no course data or activities or anything. Yet if I look in the moodledata folders for the course then materials (PDFs etc) have been copied.
I've had this problem on 1.5.3 but 2nd attempt rectified. Now trying to move a course from our 1.5.3 installation to a different installation of 1.8 to demo the courses (local laptop install) the same thing is happening - I get the label but no activities.
Looks like I'm not the only person having this problem - but very few responses here???
