 * Hi I have WordPress 4.5, running the Lumen theme and Visual Composer. Everything
   runs fine until I install Visual Composer – I get a javascript error that stops
   thje main navigation from working. If I moouse over the navigation button I see
   the url of the destination in my browser status bar below, I can right click 
   the button and ‘open link in new tab’ just fine but when I left click the link
   nothing happens.
 * I’ve contacted support for the theme but there is no effort on their part to 
   rectify it and the turnaround time is a week on each request. Visual Composer’s
   support identified the error but will not fix it.
 * The error reads:
 * (JQMigrate)
    (x) Uncaught TypeError: cannot read property ‘prototype’ of undefined(
   x) Uncaught ReferenceError: NProgress is not defined (3) Uncaught ReferenceError:
   NProgress is not defined
 * Please help. I’m reasonably au fait with using the editor to update pages etc
   and if I can be pointed to the error and offered a solution I am confident I 
   can do the work.
