 * A site I maintain still uses this plugin, and it was recently brought to my attention
   that the “insert title” button in the WP visual editor wasn’t working. Throwing
   a javascript debugger into the mix exposed errors along the lines of “no method‘
   onInit’ for undefined” or “no index ‘window_height’ for undefined”.
 * The issue I discovered boiled down to a few minor changes in the TinyMCE code,
   since this plugin was written against TinyMCE API 3 and WordPress is, at the 
   time of this writing, using TinyMCE API 4. Thankfully, though, a TinyMCE 3 compatibility
   layer is present, significantly easing the transition. (I apologize for taking
   the lazy way out and not taking the time to properly port this to TinyMCE API
   4.)
 * The two scripts in wp-content/plugins/multi-page-toolkit/buttons/js needed to
   be patched as follows:

 * I apparently missed the edit window, but wanted to add that I did go back to 
   grab the original error messages, which may help other people find this in the
   future:
 * `Uncaught TypeError: Cannot read property 'mce_inline' of undefined tinyMCEPopup.
   getWindowArg @ tiny_mce_popup.js:47`
 * and
 * `Uncaught TypeError: Cannot read property 'plugin_url' of undefined tinyMCEPopup.
   getWindowArg @ tiny_mce_popup.js:47`
 * I’ve also posted this on [my blog](http://www.p14nd4.com/blog/2016/01/24/multi-page-toolkit-plugin-insert-page-fix/),
   and may respond more quickly there if you have comments or questions.
