thank you, but I am one of the members, not all of the members profile messages at the same time to delete, I would like to reset. You say that 1 member of all the messages to delete.
Assuming you want to remove all profile posts from all member profiles, you could just truncate the xf_profile_post_comment and xf_profile_post tables.
I haven't tested that though, so take a backup beforehand if you do.
