There is a load of notifications to tell the owner of the file to share it again.
My Questions:
can i disable “serverside encryption”?
If i do so do i need to run some occ commands to get files unencrypted?
I know we must update to version 25, must i do that first or first remove the encryption?
I would be very gratefull for any hint to get “my (next)cloud” running again after the migration from owncloud.
Regards
Jan
