The date, comment, category, author stack vertically on the Blog Single Author Fullwidth page in the default install at http://blueunderground.org/blog/blog-single-author-full/. I would like to see them in one line like the demo at http://kriesi.at/themes/enfold/blog/blog-single-author-full/.
I tried setting up another Blog Single Author Fullwidth page and have the same result. I added the “Blog” Element to my advanced layout, then selecting the “single author” blog layout and on the right sidebar search for the “Select the desired Page layout” dropdown and selected “No Sidebar”.
The other Blog Single Author Fullwidth page I setup, that has the same problem, is at http://blueunderground.org/blog-wide/
Please update Enfold to version 2.1 and WordPress to 3.6 and problem should be solved. You are currently using Enfold version 2.0
