 * Hello everyone,
 * I have a problem with the theme’s customizer.
    Indeed, when I want to customize
   an item (like “Home Main Content Area” for example), the customizer doesn’t move,
   and i can read on the console a javascript error : “**Uncaught TypeError: t.onChangeSectionExpanded
   is not a function**“.
 * I already empty the browser’s cache, and i tried to customize my website with
   another theme, and the customizer works.
    Furthermore, i tried to customize another
   wordpress’s website with the the theme Fitness-Hub, and the customizer still 
   doesn’t work (but works with another theme). Finally, i tried to disable all 
   my plugins, and activate them one by one, but without success.
 * So, can you help me to find where the error comes from ? Thanks you for your 
   answer.
