Hey its working fine after 3.6.3 update. Thanks!!
When I click on Add slide or try to update images it is redirecting to the page “http://dev-joe-boxer-lnt-july2016.pantheonsite.io/wp-admin/admin-post.php”
Sorry I have sent you the production site URL, I have updated the plugin in dev environment and here is the URL
http://dev-joe-boxer-lnt-july2016.pantheonsite.io
And in console, I don’t see any javascript error.
