Not working with Mollie Payments for WooCommerce by Mollie

Hi Bas,

So after noticing that your plugin was now working with Wordfence, I set about trying to resolve another conflict with Woocommerce – autocomplete!

Finally, it transpired that Mollie recommend using their OWN plugin for Woocommerce and not the Woocommerce plugin (as it has outdated input methods of the webhooks that no longer work with Mollie) and so resolved that by using the plugin by Mollie itself.

Only to have a similar error being produced as the Wordfence plugin was giving a few weeks ago!:
Error message detected – PDF file generation aborted.
unserialize() expects parameter 1 to be string, object given
File: /home/birthinh/domains/birthinholland.com/public_html/wp-content/plugins/mollie-payments-for-woocommerce/includes/mollie/wc/helper/data.php
Line: 225

Any ideas of how I can resolve this?

Thank you!
Lisa
