You should have stated in your question which compress tool you used. Also, knowing what it was compressed to could have helped as well. Using this, it was compressed to:

//...

$(function(){
//...
      /**
       *    CENTER
       */
      $.fn.equalWmargin = function(){
            $(this).css('left',($(window).width()-$(this).outerWidth())/2);
      }
      $.fn.equalHmargin = function(){
            $(this).css('top',($(window).height()-$(this).outerHeight())/2);
      }
      $.fn.equalMargin = function(){
            $(this).css('top',($(window).height()-$(this).outerHeight())/2);
            $(this).css('left',($(window).width()-$(this).outerWidth())/2);
      };
});

You didn't have those last center functions inside the right scope. Here it is compressed:

$(function(){$("#flashMessage,#authMessage").hide();$("#flashMessage,#authMessage").css('top',0).css('left',0);$("#flashMessage,#authMessage").slideDown('fast');setTimeout(function(){$("#flashMessage,#authMessage").slideUp('slow')},10000);$("form").submit(function(){$(this).find(":submit").attr('disabled','disabled');});$("<div/>",{"id":"ajaxloading","style":"background-color:yellow;padding:7px 15px;border-radius: 5px;-moz-border-radius: 5px;-webkit-border-radius: 5px;box-shadow: 5px 5px 2px black;  -moz-box-shadow: 2px 2px 2px #CCC; -webkit-box-shadow: 2px 2px 2px #CCC;z-index:999;"}).appendTo("body");$("#ajaxloading").hide();$("#ajaxloading").css('position','fixed').html("<b>Now Loading ...</b>").css('left',($(window).width()-$("#ajaxloading").outerWidth())/2).css('top',($(window).height()-$("#ajaxloading").outerWidth())/2);});$(function(){$.fn.popBox=function(options){var target=options.target;var trigger=this;function _showOverlay(target,trigger){$(trigger).click(function(){$('<div>',{id:'overlay',css:{width:"100%",height:"100%",left:0,top:0,position:"fixed","z-index":1000,"background-color":"#222",opacity:0.3}}).hide().appendTo(document.body).fadeIn(100);$(target).fadeIn(100);return false;});}
