Hi there. Just wanted to help some folks out with some advice based on my own personal experience a few minutes ago.
Whenever you make a back up make sure you are completely logged out of wow until the backup files are copied/overwrote on top of an old backup. I had the issue of all my UI / Addons being reset for some reason. The good news is that the backup “worked” when I copied it back over thank goodness.
I had to manually re-copy the bindings files over for some reason again since it wouldn’t reset those if I moved over the entire WTF folder. (LOL, who knows why.)
Anyway just sharing.
