If anyone comes across this thread looking for a solution, I followed this and it solved my problem of permission errors. Go to Storage --> Shared Folders and select access control list to take you into the access control list menu. At the bottom of this menu, tick "Recursive". Also make sure the users have their appropriate permissions set. Make sure to save.
Great!!!
That also solves the problem for me!!!
Thank you very much, I was looking for it for a long time...
