File upload authenticated user

sorry for the much questions but i have another problem.

I need to allow authenticated users to upload their files. i have two authenticated users but if i try to upload file this message appear

error - User has no permissions to specified resource

if i enable the not-authenticated user the upload work fine and the publisher name is ANONYMOUS. this is very strange thing given that the upload has been tried only by authenticated users

How do you upload files? Is it with REST API or an SDK? If the latter, which one?

i upload with javascript sdk

Please make sure to get the latest lib from here: https://github.com/Backendless/JS-SDK/tree/master/libs

perfect now work! thanks!
