I am playing with a new website and am leaning toward the use of the Atahualpa theme and have the latest one installed (3.4.4).
On the right the first set of links is appropriately formatted. The subsequent ones are not. I am not much of a coder but I do see a div tag that isn't added to the subsequent ones.
See:http://backpacks.reachfoundation.org/ to see page source. [see note below]
See attachment of screen capture showing formatting problem.
Note - I am posting this today midday and don't plan to play with the site again until tomorrow. Tomorrow night I will be flipping themes around to demo to someone else and so if you follow the link after today the theme might have flipped over. While I am leaning to this theme, others might not feel that way.
