Home folder unavailable after upgrade til version 10


#1

After upgrading to owncloud 10 (Ups.. update server via Ubuntu Landscape service) I have a single (know of) user that cannot access his home folder. Have other users that work fine.
strong text

occ files:scan username find alot of files'.
Starting scan for user 1 out of 1 (username)

+---------+-------+--------------+
| Folders | Files | Elapsed time |
+---------+-------+--------------+
| 568     | 4125  | 00:00:08     |
+---------+-------+--------------+

Steps to reproduce
1. Open owncloud web URL.
2. Logon with user.
3. No files are shown, and the error message "This folder is unavailable, please check the logs or contact the administrator" is shown. By clicking files shared with others, some folder can be shown anyway.

Expected behaviour
Show all files in home folder.

Actual behaviour
Empty folder are shown.

Is this a local user or an LDAP user?

Have you checked the "oc_shares" table in your database?

You could try to transfer ownership to this user with an occ command.
