wordpress.com Caching

Hi from Germany!

I am having problems with wp_bannerize_pro and the caching of wordpress.com (site is hosted there)

wordpress.com has its own cache – no plugin is used for and you cannot set the cache to off!
Site is always showing the same banners, even until i set the cache manually back. Have you ever tested and a solution?

Best Regards

Thomas
