So basically, .resize function fails until I log in. What does that mean? And how that can be fixed? Almost all other functions work fine. The site is still in developement, so no live version sadly.

UPDATE:

jQuery(window).resize(function() {
        var windowSize = jQuery(window).width()
        var windowWidth = (jQuery(window).width()-60)/6;
        var windowHeight = windowWidth/1.6;
        /*grid resize*/
        jQuery('.xc-block').css({'width':windowWidth, 'height':windowHeight});
});

This is very simple script, cant really tell what can be wrong... Any thoughts guys? P.S:also no errors in FireBug...
