XF 1.3 "leave conversation" error


Active member
OK, so suddenly I am having an issue that I haven't had before... And I haven't made any changes.

Essentially, if I am looking at my conversation list I can click a check box and leave a conversation just fine. However, if I am looking at a specific conversation and try to leave the conversation from there, I get this error:

"The requested conversation could not be found."

Any ideas?
