Hi Jnui,
Thanks for the feedback.
To respond to your post, first – we haven’t heard from you in either the WordPress.org support forums, on our Github issue tracke. It would have been wise to reach out for support before bashing our dedication to supporting this free plugin.
The issue could have been due some conflict with your theme or cache plugins which could have been debugged/fixed with the help of a support request.
Sorry you had a poor experience using our plugin, in future please reach out for support so we can help diagnose whatever issue it is that your facing.
Hopefully you’ll see this post and give things another shot.
Thanks!
