Q&A Script Layout

I am having a weird layout issue on http://reptilefaq.com

If you visit the main page you will get an idea of how the pge layout is.

If you click on a category page (http://reptilefaq.com/questions/categories/amphibians/) you will see that the right column is pushed left because the Q&A area now takes 100% width ... & ...

On http://reptilefaq.com/questions/ask/ same 100% issue, plus the right nav is missing, and the bigger issue is that there is no way to ask a question. The content area isn't being displayed.

Any ideas?
