My site is built on 7.1 using Fluid Engine, and I'm adding a blog, but when I create my individual blog posts (not the main blog page) the Fluid Engine editor isn't available for me to lay out the page as I'd like. I don't even get the option to "upgrade" the post pages to Fluid Engine. Am I missing something, or is Fluid Engine just not available for blog posts on 7.1? Thanks!
