Paying with PayPal works in two ways:
- on a shop page (any):
Click the cart / shopping bag icon, where a PayPal button already appears directly. Click it and enter the further details
- At the checkout:
There, first fill in all fields (name, address, shipping method, ……), only then click the yellow PayPal button
If it „doesn't work“: have all entries such as the email address been filled in? Missing entries are marked with a * - without them you cannot continue…
