I just tried going to the wardrobe, the way that you did, and I didn't get this error. Are you still getting it?

Can you try clearing your browser's cache, and then see if you keep getting it? That tends to fix a lot of issues, so trying that may fix it.

Hey , I know it's been awhile but I wanted to check in if you are still having issues accessing the wardrobe. If so, are you trying to get to it from subeta.net or Kumos?
