Since removing a conversation related plugin from 1.1, then upgrading to 1.5 to use the default conversations templates, the conversation participants are missing from the conversation list. It only shows the conversation starter. I have no customised templates relating to conversations and no outdated templates. After the upgrade I "reverted" conversation_list, conversation_list_item and conversation_list_popup. I just created a new style with no parent, and they don't show in that either. Any ideas, it must be something simple like an option somewhere I'm missing? Here on Xenforo the participants display properly in my inbox.
