Hello,
You can test the identifier by url
www.penelopeestilosa.com/mturbofrontend?identifier[]=XXX, where XXX is the name in layout of dynamic block (cart_top, cartsidebar etc...).
The settings depends on your theme. The mini cart block must be set in "default" layout, it must be displayed on all pages, else you cannot use as dynamic block.
I'm not able to say what is problem if I don't see your layout files and your template files. You can purchase the 1h paid support (
www.artio.net/e-shop/support-services/magento-support-1h) for profesional settings of M-Turbo, if you want. In this case we try to set it. For support we would need to access to admin (only for M-Turbo and Cache Management) and FTP to your website.
