I deleted a post from my Message Wall a couple of weeks ago. When the wiki was migrated to UCP a few days ago the post returned. Neither delete message nor report message options in the menu work, nothing happens when I choose them. I want this post gone from my wall as I find its title insulting. What can I do? TIA
