This fix addresses an issue wherein additional created users could have access to exclusive to master services and packages. These services are Plex, BTSync as well as the Web Console.
To add this patch to already installed systems, do the following:
wget -q https://github.com/Swizards/QuickBox/blob/qb_u_1604/rutorrent/home/inc/panel.menu.php .
Works like a charm, thanks for the update!
