Strange change

In the new version it is black and white and I guess you forgot to delete the cash after updating and that is why you realized it now. So normal behavior.

Thanks for your answer.I really dont like it being black and white,is there any way to get the icons in colour?

This issue is already discussed here somewhere. Just search for icons or coloured icons. They have already given some advices.

Here is the solution for anyone that is struggling to get your icons back in colour add the following code in your functions
`add_filter( ‘wc_stripe_payment_icons’, ‘change_my_icons’ );
function change_my_icons( $icons ) {
// var_dump( $icons ); to show all possible icons to change.
$icons[‘visa’] = ‘‘;
$icons[‘mastercard’] = ‘‘;
return $icons;
}

    $icons['visa'] = '<img src="https://www.example.com/wp-content/plugins/woocommerce/assets/images/icons/credit-cards/visa.png" />';
    $icons['mastercard'] = '<img src="www.example.com/wp-content/plugins/woocommerce/assets/images/icons/credit-cards/mastercard.png" />';
