 * Plugin works great, except I can’t get the lightbox to work on my site. I’ve 
   disabled the previous lightbox plugin I was using, still no go. [http://www.christini.com](http://www.christini.com)(
   youtube videos on home page).

 * Can you please try with development version [https://downloads.wordpress.org/plugin/youtube-channel.zip](https://downloads.wordpress.org/plugin/youtube-channel.zip)(
   simply extract files over old plugin through FTP).

 * Downloaded and installed, still not showing the lightbox. Here’s a sample page
   where in the sidebar I’ve put the widget…

 * It’s in there as a class, and it appears like all of the scripts are loading 
   up in the header and footer.
 * I am seeing this error in the console:
 * `TypeError: undefined is not a function (evaluating 'jQuery(window).on('load',
   function(){ytc_init_MPAU();})')`

 * Hi again,
 * MagnificPopup require jQuery at least v1.7.2 (best if it loads v1.11.2).
 * Something enqueue file [http://cdn.jquerytools.org/1.2.6/jquery.tools.min.js](http://cdn.jquerytools.org/1.2.6/jquery.tools.min.js)
   which activates jQuery v1.6.4 (instead WP bundled version), which is too old 
   and does not support [$.on()](http://api.jquery.com/on/).
 * To check this, you can open console in Chrome (F12) and enter following code 
   to see version of active jQuery (then press Enter key):
 * `jQuery.fn.jquery`
