Hello, I'm using the latest version of Woocommerce with WordPress 3.5.1 (Default Twentyten Template). Everything is working fine except the variations. You can see an example in this link: goo.gl/j5i3s
Whenever you choose an option, after clicking on it, it simply goes back to "Choose an option" and nothing happens. There are no errors shown in the JavaConsole, and there are no problem of plugins either (I have disabled all plugins except Woocommerce and the same result).
Because of this bug it is not possible to purchase the product, because the "Purchase" button never appears.
Maybe someone can help me. Thanks.
