Blog bubble button
 

Hi,
In our blog, we only want administrators to be able to create a blog. We took care of that; however, now when an unregistered user goes to the Blog page, the bubble button that says "Create New Post" is still there. When the unregistered user clicks on it, it says it was disabled by the administrator. The bubble is NOT there with registered users, which is what we want. Why is it showing up to unregistered users and how do we get rid of it?

How do we get rid of that button altogether?

version ?
