 * Hi there,
 * first of all, thank you very much for that amazing plugin!
 * We are however facing an issue. We are using another plugin to track the incoming
   traffic on our website. >> [https://wordpress.org/plugins/utm-tracker/](https://wordpress.org/plugins/utm-tracker/)
 * That plugin basically tracks the UTM tags as well as the referral URL and write
   them in a cookie.
    We have no problem with the UTM but the referrer is blocked/
   cached by fastest cache. We would like to exlude it somehow but even after excluding
   all the cookies and the JS from the plugin utm tracker, it still doesn’t work.
 * Bellow is the part which should be “dynamical” displayed but doesn’t work.
 * Thank your for any tip or help!

 * thank you so much.
 * but PHP does not work when the page is cached because the page is saved as a 
   static html file. you need to handle the problem with Ajax.
