 * Hi,
 * Thanks for this plugin, really works in reducing page load time.
 * But I’m receiving an JS error message when the FOUC removal option is activated:
 *     ```
       TypeError: $ is not a function
       ```
   
 * If the affected Javascript inline code is removed from the core.php file (line
   94), it doesn’t seem to affect anything.
 *     ```
       <script type="text/javascript" >
         $(document).ready(function() {
           loadeddocument();
         });
         </script>
       ```
   
 * Is this snippet necessary for something else? I just would like to check.
