dgmsta11 on "[Plugin: WP Super Popup] Doesn't Show on Every Page"

I am having trouble with the plugin. It works great on full page pages, but it won't pop-up or show up at all on pages that have a side column (like the homepage). Any ideas?

http://dirtygirlsministries.com — doesn't show
http://dirtygirlsministries.com/?page_id=54 — works great
