The update on the 22th broke a lot of addons… it’s normal.
Unless it’s an actual bug with Blizzard’s API, they won’t fix it. It’s up to the addon developer to update it to be compatible with the latest version of the game.
So… update the addon (if an update has been released) or don’t use it anymore (if the author has abandoned development). It’s always good practice to keep your addons up to date.
