Hi, the light box script used in this plugin is not compatible with jQuery 2+ and probably never will be… Unless I suddenly get a lot of time and inspiration… or help…
Sorry.
RavanH, We can guide to help compatible.
Functions or files that we should start to look?
What kind of test suggest?
A good start would be:
1. Set WP_DEBUG in wp-config.php to true
2. Install the development version of Easy FancyBox from https://downloads.wordpress.org/plugin/easy-fancybox.zip
3. Install the plugin jQuery Updater
4. Test Fancybox in the Chrome browser and use the developer tools (F12) Console tab to watch for errors related to or jQuery.
