Ok, I was able to see the problem. It only happened after I logged out and then logged back in. It came back as soon as I did a hard refresh (Shift+Refresh in FireFox), so I think it may be a local cache thing.
I also switched the module caching to Memory which may help and is definitely better for performance.
I have attached a picture to show you where the Admin and Host links are in the control panel (bottom right on your site).
Let me know if it still has problems after you clear your local browser cache.
