For a customer, I've installed to the new version of owncloud server, but now when users upload files and share with others there are a problem. I've old file in the folder and an user upload one new file.
The other user open the shared folder and he see the two old files but not the new file. He needs to logoff and logon again to his session to see the new file. When my customer alerts me, It happens with many users but never with my "admin" account.
I checked the rights and the owner (www-data and chmod 755). Everything is ok and i don't understand.
Operating system: Debian 8.5
Web server: Apache
