The plugin is tested and fully compatible with WordPress v4.3.1. The issue on your site is most probably caused by some conflict between the plugin and the theme or another plugin you are using.
We would really appreciate if you could change the 1-star rating you left, as this is certainly not a plugin issue, and it is not true that the plugin is incompatible with WP 4.3.1.
If disabling the plugins and switching to another theme does not solve the issue, please open a new thread in our community forums, and we will help you: http://community.mythemeshop.com
