I can't delete a post
If you're on a team blog and are trying to delete a post that someone else wrote, you need to contact your blog administrator to delete it.
If you've already followed the instructions on how to delete a post but the post still appears on your blog, then you probably just need to republish your blog.
Note: If there's only one post on a blog, you can delete it from your account, but it won't be removed from the blog, since there is nothing to replace it with. You can either make a new post, which will replace the deleted one, or you can delete the entire blog if you don't want it anymore.
