We upgraded from 2.2 to 2.7 last week. Everything was fine with the exception of a missing link in each week. We have a link for uploading a file for each week that we call "Research Paper." Now after upgrading Moodle, the links are missing. I checked the gradebook and the item is there.
Ok. I figured it out. I had to go to the administration and at the bottom there was a way to fix those assignments that did not upgrade.
