I recently downloaded a theme that incorporates ajax for a cool slide-y effect:
http://www.jackson-pearce.com (click About Me to see an example).
However, when I click the FAQ page and allow the theme to create the URL using Ajax http://jackson-pearce.com/#!/faq, the accordion feature of the plugin doesn't work-- everything is already expanded.
I've found a functional workaround by creating a custom URL that points directly to my FAQ page, skipping the Ajax/#! aspect, but obviously I lose the scroll effect when I do so. I'd love to keep the FAQ plugin, and also the scroll.
