When I try to set the display order number from my inventory, I get a "working" animation and then the number box is reset to blank, with no changes having been made in the display order.
What OS and browser are you using? I just tested with your shop, and was able to move item 2 to number one (then back again so as to not mess with your sorting)
What browser do you recommend? I have same problem with display order using FireFox (I'm on a Win7 now, waiting for my Win10 in a couple of weeks) but I have other browsers I use for for testing webpages, just let me know which one to use. Thanks
I use Chrome in Windows 7. Whatever the issue was, it appears to have been resolved somehow, somewhere.
