 * Hi, 1st off, great plugin.
 * Sorry, cant link to the page as its on localhost.
 * I am using Salient Theme and am getting a .js conflict
    **Uncaught TypeError:
   Cannot read property ‘push’ of undefined – TweenMax.min.js..**
 * The pop up still works if I disable the Themes animation between pages option,
   but as preferred obviously, would like to nut out these errors prior to pushing
   live. I have commented out the PHP error that appears as mentioned in a previous
   support post.
 * Please let me know if you need anymore information.

 * [@jstead](https://wordpress.org/support/users/jstead/) – You don’t have any previous
   posts that I can see, so I’m not sure what you mean by PHP error.
 * Sounds like your theme is either including Rev Slider or using Greensock animation
   platform for animations. If it includes Rev Slider this is a known bug, and updating
   Rev Slider will resolve the issue. If not it sounds like your theme is not properly
   calling its GSAP js files in a way that allows us to detect and not load a duplicate
   copy. If multiple copies are loaded this is the type of error that occurs.
 * Hope this helps.

 * Hi, sorry didn’t mean my previous post but one of the resolved ones from someone
   else.
 * Ok makes sense. I Remember seeing Greensock and GSAP during my googling for answers
   and if I enabled the animated transitions between pages, the plugin doesn’t work
   altogether.
 * I will have a dig around in the theme side of things.
    Thank you for the quick
   response.
