The latest github download works a treat for me, especially for a payment module like eWay.
Made some tweaks such as pre-selecting eWay as payment method and added a few bits and pieces which are only relevant for one of my stores. All good!
But found another little 'boo-boo':
In the file includes/templates/template_default/templates/tpl_checkout_one_confirmation_default.php the
$editShippingButtonLink takes me back to the home page instead to the address book for editing the shipping address in the order.
It looks like that
$editShippingButtonLink does not carry from the previous page.
So in the file includes/modules/pages/checkout_one_confirmation/header_php.php below line 95 I added
Code:
$editShippingButtonLink = zen_href_link (FILENAME_CHECKOUT_SHIPPING_ADDRESS, '', 'SSL');
and that did the trick for me.
