Hi Xtemos,
thanks for your quick response.
1 & 3 & 5) Unfortunately the plugin’s developers claim that their plugins works with the basic themes provide by woocommerce and that should be your responsibility configure them to make them work. however, I will try to replace the third-party plugins with default plugins of your theme, hoping to get the result I want. Thanks for the link to the video tutorial.
4) I have followed the thread on the WooCommerce bug v. 2.6.12, but I have already installed the later version v. 2.6.13, as I reported you.
5) I have already set the custom order of attributes with drag & drop, but unfortunately does not work.
You may be kind enough to help me?
I have seen that you have released a new version of your theme: do you believe that if I make the upgrade can solve these problems?
Thank you very much in advance.
