I did a quick test and found a few bugs:
- After adding a bitcoin block (or blocks of products), I can't edit/add the exact product price (I can only edit the image, title and the description parts).
- The payment page is always in "Russian".
Thanks for your comment. We understood that was difficult to find where edit the price. Now you can edit the price when you click on it. We fixed the language bug in Empty templates. We are continuing to work with other templates.
