Hi there,
Thanks for choosing our IntellyWP products.

What you mean with "not working"?
Please try to be more specific and also send us some screenshot about the plugin configuration and some public URLs where we can test it.

With this information that you can send at our [email protected] will be a pleasure to help you, Simon.
