I tried to update my owncloud 8.2.7 to 9.0.5. But while the db was upgrading my sql server ran out of disk space and the db crashed. I tried than to restore the db with an backup. But i had to realize that i didn't have a full dump.
So i decided to install a new owncloud instance. After installing, i activated encryption and created my users with the same passwords as before. After that i copied the old data path to the new one and started an occ files:scan.
After that i was able to access most of the files. But some files cannot be opened, downloaded or synced. I found out that the download stops at the moment when the original file size (without encryption) has been downloaded.
I already search in oc:filecache for that files. The encryption ist set to 1. And the file is really encrypted. I downloaded it via ftp.
So...has anyone an idea? In owncloud log i found the error Cannot modify header information - headers already sent by ...
