My hosting company had a MySQL problem. This coincided with an update to Moodle. They say that they did nothing to my Moodle itself, however, I suspect that they performed a restore. I have just realised that the activities in weekly classes that were entered as 'assignments' are now missing. When I check the gradebook they are listed there.
I looked at a previous run of the same course, (for which there was a full set of student submissions and marks) and again, the activities that were assignments are missing but they are in the gradebook.
I have now checked other courses with assignments and they too are missing, so this appears to be a site wide issue.
Can anyone throw any light on what might have happened, and how I can restore the assignments?
Thanks (in a mild panic), Graham
