[Risolto] Multi-Currency

Background of the issue:
I want to add the Multi-currency switcher to the product page on my site link nascosto. I am using a product-configuration plugin, and you can't add to cart directly from the product page. Example: link nascosto

Symptoms:
The Multi-currency switcher is not displayed on the product page.

Questions:
Is the product-configuration plugin causing the Multi-currency switcher to not display?
How can I add the Multi-currency switcher to the product page?
