Hello,
Thank you for reaching out.
I’ve checked your website and I am not seeing W3 Total Cache installed. I do see, however, that you have some other caching solution. Can you please confirm that?
You can check our Premium support offer on the plugin page Performance>Support.
To configure the plugin for you you can select a Plugin configuration solution.
I strongly recommend removing any other caching solution to avoid conflict and breaking of your website.
Thanks!
