Cant enable/disable add-ons

[_Zodiac]

As title says im unable to enable / disable add-ons using the ingame reloadui option. I tried to repair the game, deleted and let game recreate the launcher settings file but nothing worked

Also none of the changes i make using my addons save. every time i log in everything falls back to lets call it 'original status'

Additionally i keep getting messages for changes in MotD from all my guilds every single time i log in to any of my characters

Any suggestions?
