MarketPress and missing Paypal button

MarketPress and missing Paypal button

Hi,

I am using the MarketPress plugin togeteher with Paypal Excpress Checkout (in sandbox mode), and it all works fine, apart from one thing:

On my checkout page https://metrodesign.dk/store/shopping-cart/checkout/ the image or logo for Paypal is not shown.

The reason for this is that, in the code-behind file for the checkout-page, there is this URL to a Danish Paypal image: https://fpdbs.paypal.com/dynamicimageweb?cmd=_dynamic-image&buttontype=ecmark&locale=da_DK and it does not exists – at least the URL does not work.

My plan is now to exchange the Danish not working URL to this English working URL: https://fpdbs.paypal.com/dynamicimageweb?cmd=_dynamic-image&buttontype=ecmark&locale=en_GB

My problem is that I do not know how to do it?

I think that I have to edit some code in one of the MarketPress modules, perhaps this one:
wordpress-ecommerce/marketpress-includes/marketpress-gateways.php, but I am not sure.

Can anyone help me out, please?

Thanks in advance.
