Custom basic .js from theme dir prevents Splashify module from working
Looks like simple syntax error :

(function ($) {
  /* Slideshow */
  Drupal.behaviors.MYSITE = {
    attach: function (context, settings) {
      $(".carousel").jCarouselLite({
        btnNext: ".next",
        btnPrev: ".prev"
      });

      /* Rollover info */
      $(".block1").hover(function(){
        $(this).find("span.info").stop(false, true).fadeIn("fast");
      }, function(){
        $(this).find("span.info").stop(false, true).fadeOut("fast");
      });

      // Class for every 3rd row.
      $(".view-flavor-listings .views-row:nth-child(3n-3)").addClass("diff-margin");
      $(".view-content-inner .views-row:nth-child(5n-4)").addClass("diff-mrg");

      /* slidePager */
      $('.pages').slidePager({
        last:6,
        borders:1,
        change:function(n){
          var els=$('.thumbs li').removeClass('mrk');
          els.eq(n).addClass('mrk');
          els.eq(n+1).addClass('mrk');
          els.eq(n+2).addClass('mrk');
          $('.thumbs li').css('opacity',1);
          $('.thumbs li:not(.mrk)').css('opacity',1);
        }
      });

      // Make Plupload default.
      $('.filefield-sources-list').each(function() {
        $('a.filefield-source-plupload', this).trigger('click');
        $(this).hide();
      });
    } // attach
  } // behavior
})(jQuery);
