When I try to kick someone from my guild and I hit “yes” it just gets stuck at that and does nothing. This is a significant problem, the 2nd best option I could do was just make them unable to talk in chat.
I tried turning off all my addons, this wasn’t the issue.
I’m experiencing the same behavior on Nightslayer (the pvp realm).
Was having the same issue on the hardcore servers. Seems to be an issue with the Guild UI.
You can fix this by going to Interface > Display > Classic Guild UI (all the way at the bottom) and unchecking this option.
