The addon is no longer working in Classic. I don't get any errors, ctrl+C just opens my character info instead of the normal panel with the link. This happens with all addons except for this one disabled, so it's not a conflict with something else.

Thanks for the addon in general, it saves me so much time!

I just checked, it is bound, but the addon is magically working today. I didn't change anything, I have no idea why it didn't work yesterday. Sorry to waste your time, and thanks again for the awesome addon!

No worries. There currently is an issue where the keybind will get unbound on UI reloads (but fixes itself after a relog) - that might have been what caused it.

It sounds like the keybind might have gotten unbound. If you go to Key Bindings -> AddOns, is "Generate Wowhead Link" bound to anything?
