After upgrading to 1.6 product has zero price in the cart

Hello, yesterday I upgraded the plugins, and yours is now the version 1.6. However, after that, I realized that when I add to the cart a product by naming my price (no matter what decimal punctuation I use) the resulting cart contains the product with a price of 0.00.

How it comes? Thank you very much for helping. It is quite urgent to fix this problem, as the products are already online

Ciao
