Scripting error on top of page

Hi

I'm getting the following error on top of my blog pages;

EasyBlog.require() .script('layout/responsive') .done(function($){ $('#ezblog-head #ezblog-search').bind('focus', function(){ $(this).animate({ width: '170'} ); }); $('#ezblog-head #ezblog-search').bind( 'blur' , function(){ $(this).animate({ width: '120'}); }); $('#ezblog-menu').responsive({at: 540, switchTo: 'narrow'}); $('.eb-nav-collapse').responsive({at: 560, switchTo: 'nav-hide'}); $('.btn-eb-navbar').click(function() { $('.eb-nav-collapse').toggleClass("nav-show"); return false; }); });

I tried to switch the Enable responsive layout off, but that breaks the page. It works fine on my localhost.

Can you please assist
