The issue only occurs in this child style of Whisper2 so it must be something I've customized and is related only to guest view. I've tried the obvious and disabled other addons one by one with no change.
The addon is Rate Threads with Stars but I don't believe its the addon's fault. I'm 99.9% certain the issue is caused by me
How should I best hunt this problem down?
