I'm using Joomla 3.2 and EasyBlog 3.9.15110
I've installed and enabled the autoposting plugin, setting it to the desired article category.
I wrote a new blog entry and published it. It does not autopost.
If I attempt to autopost from the backend, the option is not available - says the post must be published first.
As you can see from the attached screen shot - that post is published, frontpage, and featured - yet autopost is not available.
