I am hoping someone out there in the community can help me understand this problem I have. Yesterday I was looking into upgrading the assignment 2.2 to the new version. As an interim measure I thought I could hide the option to choose assignment 2.2 from the activity choice. When I did this it deleted all 2000 assignments from the VLE, no warning no documentaion.
I managed to get a back up of the database from the day before and all the assignments have reappeared but not I am getting errors saying 'invalid module ID' or 'Can not read file, either file does not exist or there are permission problems'.
When I look in the database I can see the content and I can download files but the links dont work in the front end.
Please could anyone let me know when this could have happened just from hiding a assignment type and if I have any chance of rectifying it?
I am using Moodle 2.5+ (Build: 20130627)
