Problems with CMS editor and FullpageJS

You do not need these if you place all custom code either in Site Footer or Page Footer code areas, as jQuery will be already loaded by Webflow:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>

// needed to use noConflict
$160 = jQuery.noConflict(true);

So remove your own jQuery include, and change your code to this:

Webflow.push(function () {
  // check is the CMS editor is there
  if (Webflow.env('editor') != undefined) {
    $('#fullpage').fullpage({

    });
  } 
});
