So then, I went on another test website of ours, which, I know private conversations are allowed and just to be sure I double checked that in my profile page, the 'start a conversation' button was there. But when I turned it off(through ACP >Options> User Registration> Initiate Conversation With This User> Nobody), and then refreshed my pages, the 'start a conversation' button was still there! It was really weird.
Could someone tell me how to resolve this problem? Is this a bug? Thanks a lot!
