File Share module not working

After downloading the file share module from oer2go website, i tried ti upload a file to my Raspberry Pi, but although it reads as success, when you go to view in upload, there is nothing there.
It seems some errors occurs via resync, please i need help

Same problem for me - anyone know anything about this?

"sudo chmod 777 /var/www/modules/en-file_share/uploads will fix it.
