Why is the payment method not clickable by the buyer?

When paying, some buyers cannot click the Payment by credit card button, the cursor does not transform into a hand like a clickable link, and if the buyer clicks on it nothing happens.

In this case, make sure that a third party analytics module is not involved.

For example, if you are using the Google Analytics Pro module, you will need to enable the option: Your customers use ad or analytics blockers by setting it to YES.
