Great fix for the Solostream Premium Theme. I was going crazy trying to figure this out...
However I have a couple of problems. First when I put the shortcode into the "Display 468x60 Header Ad" space on my Solostream WP-Bold the first menu item in the Top Navigation menu is pushed down about half a line.
Second issue is that if I activate the "Display 468x60 Post Ad" the remaining content, post (all categories)is centered and the sidebar is pushed below all page content.
Any idea what is going on?
