Hello,

When people go to the checkout and select the credit card payment option and hit the payment button, they get an error page with this text: 0 call to undefined function mcrypt_encrypt(). I really have no idea what it is. Can you solve my problem?

Problem solved by putting PHP back to PHP7.1. where the module is still active.

Best regards,

Nico

Hello,

You're using a payment plugin which is not up-to-date and do not support PHP 7.2.0 for its current version.
Best is to know which payment plugins you have installed (and enabled) in your website..
