drupopuppis on "[Plugin: WP-Filebase Download Manager] WP-Filebase Tree View not working"

Hi since today I can only see and expand the files on tree view if I am logged as an admin.
I have tried to set off any other plugin but none are conflicting with Filebase.

I am running on WP Version 4.1.1 and latest WP-Filebase

Anyone..?
