Can't Drag & Drop Categories
I just installed Vanilla using the softaculous software, and immediately noticed that I can't drag and drop my categories. It seems to work in the administration area, but when I view the forum on the frontend, nothing has changed. This is quite frustrating since I need to have my categories arranged alphabetically.
