# Slideshow Error – "This slideshow requires JavaScript"–> (admin-bar-v2.js:47)

 * Need Help 🙂
 * All blog posts slideshows now produce this error “This slideshow requires JavaScript”
   ONLY when I am logged into the WordPress Admin at the same time. The error disappears
   when I “log out” of Admin.
 * This just started occurring after I updated several plugins, and one was “Jetpack”…
   so not sure if related.
 * * WordPress v 3.5.1
    * Jetpack Installed * Genesis Framework with Child Theme*
   All plugins up to date * Google Chrome v 26.0.1410.64 m
 * 1) EXAMPLE URL = [http://bit.ly/18dWO7U](http://bit.ly/18dWO7U)
 * 2) POST HTML ERROR (When logged into Admin)
 * <p class=”jetpack-slideshow-noscript robots-nocontent”>This slideshow requires
   JavaScript.</p>
 * 3) JAVASCRIPT CONSOLE ERROR
 * “Uncaught TypeError: Cannot call method ‘match’ of undefined” (admin-bar-v2.js:
   47)
 * LINE 47 –> var lang=$(‘#wpnt-notes-panel’).attr(‘lang’);if(!lang.match(/^en/)){
   src+=(‘&lang=’+lang);}
    Uncaught TypeError: Cannot call method ‘match’ of undefined
 * I have reviewed all forum posts but cannot find this same issue. Can someone 
   please assist?
 * Many thanks!

 * I am having an issue with admin-bar.js as well
 *     ```
       TypeError: $(...).on is not a function
   
       return true;t.hidePanel();});$(document).on('keydown.notes',function(e){var keyCode=wpNotesCommon.getKeycode(e);if(!keyCode)
       ```
   
 * this error is gone when I am logged out
