I have a video website with a submission form that gives anyone who registers (subscriber role) the ability to embed any YouTube or Vimeo video they like as a post: http://ViewsFor.Me I'm in the process of trying to implement the WP User Frontend plug-in into my website to allow those users to go in and edit/delete the posts that they created if they like.
I am testing it out now and it appears that the edit page accessible through the dashboard works just fine and allows them to edit their own posts, however on the dashboard page (http://ViewsFor.Me/dashboard) the delete function always fails with the "You are not the post author. Cheeting huh!" message even though the accounts I tested it on were clearly the post author.
I also attempted this with the author role to see if the subscriber role was preventing users from deleting and got the same message.
