Polylang update breaks Mollie Payments for Woocommerce

Hi there,

I really love your solution for multilingual websites. It simple and easy to use, that’s why I advice Polylang for all clients that want multilingual websites.

Clients of mine that use both Polylang (regular version) and Mollie Payments for Woocommerce (with Woocommerce of course) experience errors in handling orders. The developer of Mollie Payments for Woocommerce told me the webhook is not working properly. This first started after I udated both Polylang to 2.3.6 and WordPress itself to 4.9.6. I tried reverting Polylang to a previous version, but to my surprise, that had no effect. Here’s the error I got:

2018-05-19T01:11:54+00:00 DEBUG mollie_wc_gateway_paypal: Start process_payment for order 7582

I hope you can help me, both clients are starting to complain because of double payments and angry clients in their webshops. Thanks.

Best regards,

Bas Poppe
