So about a month ago, I logged in and noticed that when I hover over my shops names through the 'Your Shops' bar, there was a little dark triangle with an explanation point in it right next to it. I thought it was nothing until recently I've been logging back in more and when I click onto 'Your Shops' nothing comes up as if I have no shops and I cant place things in my shops anymore. I can still look on their page and I can still see my shops on my profile page but I cant really use them anymore and I don't know why.

[.K.Rouge] This guide should help: New Shop Guides

Thank you so much! It did help.
