Looks like you have a number of issues. Using the Web Inspector in Chrome, you have 12 403 errors and 2 404 errors. The 404’s are related to your CSS and your Javascript files.
Because your stylesheet isn’t found, it looks like a DIV with an ID of #cboxOverlay is covering up all the content. Once you set that to visibility: hidden;, you can see the rest of the site. However, you still have a bunch of 403’s which suggests that you still have permissions problems.
