First — thanks for giving me your URL, it really helps to debug!
1) In the TopBar CSS Option C – removed the “position:fixed”. This will push your page down BUT the TopBar will disappear if the user scrolls.
2) I played around with your site with Chrome’s developer tools. In your theme’s style.css, try changing your padding-top from 5px to 50px for #header. Should be line 127 and this it what is should look like after you edit it:
For some reason, I don’t see the TopBar in your sites code anymore.
Can you disable your existing TopBar and create a new one?
Go ahead and change any options — but do not change the CSS Option C.
Let me know if that works.
Also, when I look at your site, I see a black Admin Bar at the very top (with “Login and Directory Dashboard”.. I think that it will occupy the same area that the TopBar would and will hide any TopBar.
