Are you using external storage, if yes which one: local/smb/sftp/...
local on a glustermount

Are you using encryption: yes/no

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

LDAP configuration (delete this part if not used)

ldap works for all users

Client configuration


Operating system:


Web server error log

Insert your webserver log here

ownCloud log (data/owncloud.log)

Insert your ownCloud log here

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log
b) The network log 
c) ...

What is the difference between the user in question and the other users?

How does he access owncloud?

Can you see errors in the owncloud.log file when the user accesses owncloud?

same as all other users
access via client and webbrowsers
log shows nothing

./occ files:scan ###user-hash#####
Exception during scan: Parent of share should be unique

Did you try the occ files:clean command?

Do you have external storage and how are they mounted?

I think you can try this fix


going to try occ files:clean first
let them check if this works for them first

Your suggestion fixed my problem!

Glad I could help you out :slight_smile:
