Just before the crash, all my action bars reset to “classic” mode and now I cannot rearrange them to what I had before this happened. Why not??
UI Changes, Macros, etc do not save if you are kicked out of the game via means other than the Exit or Logout buttons. I can’t tell if that’s the issue you’re running into or not.
Might I suggest you transfer this post to the Technical Support forum. You have a chance of having a blue response and/or more assistance along technical lines there.
If you’re having issues with Edit Mode working, try deleting your cache folder and do a UI reset.
