 * Hi Tom
 * Thanks for your reply.
 * If I understood right, you suggested to install “W3 Total Cache Purge All Page”
   plugin.
 * It did not solve the problem.
 * Thanks

 * Hi Guy,
 * The plugin is just called ‘W3 Total Cache’. (The one you’ve mentioned sounds 
   like an addon plugin).
 * Once installed you’ll need to enable CSS minification in the plugin settings.
 * Regards,
    Tom.
