 * That is because most likely you are using a caching plugin and this plugin does
   not work with caching plugin.

 * I use wp super cache and autoptimize . I have added snippet code jn functions.
   php but apparently not working.
 * Is there a cache plugin could working with your plugin ? Could it be due to varnish
   cache on server side ?
 * Thank you !
