On Firefox, all boxes were blank on the configuration screen. However, remember when configuring certain things like ‘Media Streaming Add-on’, items might not appear if not using the Chrome browser. If anyone else hits this bug, you can use the ‘Media Streaming Add-on’ to customize your menu with fewer items. That way I wouldn’t be hitting this bug with getting ‘access denied’ when paging down beyond the very first page of the first screen. I was able to reconfigure the remote access menu for this qnap nas with fewer items in the menu, so I could get access to the ‘Folders’ menu item, which was previously on the 2nd page. All I wanted to do is get to Folders which is located on the 2nd page. Yet I can select an item in the first screen and go through more screens after that fine. Nothing work! It is so strange it will not let me go beyond the first page of options without getting access denied. I tried going into Media Receivers, changing the AVR device 'user profile' to Guest (from Default), I also tried setting it to Admin. I haven't made any changes that I'm aware of. I used to be able to go through the menus on this qnap from my AVR previously.

The AVR can go through all the menu screens on my other NAS product (Kimax) fine. But if I select any item on the first screen, like Artist, I can go through screens of artists fine. But now when I go to select Folders, which is not in the list of items on the first menu page, so I go down past the last item on the first page to get to the next, I get knocked off with 'access denied'.

On my Yamaha TSR-700 AVR, when I select Server and connect to my TS219II, I get through to my music menu ok, as I have in the past.
