When i tried restoring from old course backup during this week everything went fine(it seemd), but when i started to check out the new features of 2.8.5+ in the restored courses I noticed that some of the functionality had dissapeared from forum(couldn't subscribe to get email copies of individual discussions).
Is there a way to fix this? Is there anymore acitivities affected if i backup and restore old courses?
Do i need to upgrade the old platform before i do course backup to be able to get the functionality, just a simple course backup/restore is not enough?
Just a note, when I create a new forum activity in the restored course, the functionality appears, seems only to be on the restored ones...
