Hello Eva,
I just upgraded to the latest version of Woocomerce (2.3.2) and plugin payment gateway (http://www.redsys.es/wps/wcm/connect/redsys/a144eacd-5707-4bee-b75c-866b1491815d/redsys_woocommerce_V2.0.zip?MOD=AJPERES) and there have been several problems:
a) 10 copies out of date templates are displayed.
b) In “Edit my cart” now 2 buttons are displayed: “Continue” and “Proceed to checkout”. When before the update only showed the “Continue” button.
3. In “Checkout page” the payment block is duplicated (one payment block before payment button and the same block after the button).
Awaiting your prompt response to correct these bug.
Thank you.
