I can't log in, it requests htpassword before I can reach wp-login.php.
However I think I can see the problem right now. Some minification plugin minifies all the scripts before the jQuery scopes are loaded to the page. Since the plugin scripts are loaded earlier then the jQuery it naturally throws an exception and halts every script afterwards.
I rather recommend W3TC caching plugins minification. It works 80% of the time, which is far better than any minification plugins on the market. But you need to prepared for massive testing. It took me 3 days to figure out the proper script order and exceptions on this site for minification.Best,
