Like lhungil said, you should post your issue on Numinix's board; it's looking like the CSS/JS Loader is the culprit. From your homepage, you've got the following in your page's header:
Code:
<base href="http://d132s.southshorepizza.net/" />
<link rel="canonical" href="http://d132s.southshorepizza.net/" />
<link rel="stylesheet" type="text/css" media="print" href="includes/templates/classic/css/print_stylesheet.css" />
<link rel="stylesheet" type="text/css" href='/includes/templates/classic/css/stylesheet.css' />
<link rel="stylesheet" type="text/css" href='/includes/templates/classic/css/stylesheet_css_buttons.css' />
That extra / before the non-print stylesheet specifications is what is killing you when you go to shared SSL.. The fact that the print stylesheet comes before the display-related stylesheets is a clue that the CSS/JS loader is involved.
The CSS/JS loader code is installed, just not minifying ...
