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) ...


this looks very strange to me:

Could it be possible that you have moved the data directory from /var/www/html/owncloud/data to /media/owncloud/data/ in the past without following the documentation on how to update the database entries?

Ok, i just had the idea to search for this error:

in the ownCloud bugtracker to see if this was reported to the ownCloud team and it looks to me that indeed something was already reported to them:

I move the data dir after installing owncloud. So this is two years ago.

So this look like the issue from individual-it but the oc version is 10.2.1
