Hi,

please always disable 3rdparty apps first when facing such issues. In this case disable "apporder". Afterwards empty your owncloud.log and try again.

All 3rdparty Apps are now disabled.

So the file seems to not exist on your filesystem on the server.

I removed every Files on the owncloud server and now it works again. Thanks for your help :slight_smile:
