If you have installed the latest V4 click version and are getting this warning:
Notice: Undefined index: payment_option in /var/www/html/wp-content/plugins/yhp-worldline-gateway-click/yhp-worldline-gateway-click.php on line 157
The fix is easy.
Just head over to your settings and stipulate a payment method. Then save. This should resolve the issue.
Our next version will include better error handling and reporting.
