Hi,
You may try this trick which i believe will solve the issue you are having.
Open this PHP file:
/templates/YOUR_TEMPLATE/html/com_virtuemart/cart/select_payment.php
and look for this line;
<form method="post" id="paymentForm" target="_parent" name="choosePaymentRate" action="<?php echo JRoute::_('index.php'); ?>" class="form-validate">
replace it with this:
<form method="post" id="paymentForm" target="_parent" name="choosePaymentRate" action="<?php echo JRoute::_('index.php?option=com_virtuemart&view=cart'); ?>" class="form-validate">
Then open this PHP file:
/templates/YOUR_TEMPLATE/html/com_virtuemart/cart/select_shipment.php
and look for this line;
<form method="post" id="userForm" target="_parent" name="chooseShipmentRate" action="<?php echo JRoute::_('index.php'); ?>" class="form-validate">
replace it with this:
<form method="post" id="userForm" target="_parent" name="chooseShipmentRate" action="<?php echo JRoute::_('index.php?option=com_virtuemart&view=cart'); ?>" class="form-validate">
So visitor will get back to
vintage.preart.kylos.pl/cart page after they select their payment or shipping method. I am sure this will eliminate the issue you are having.
