    When I upgraded these 3 plugins (name|old|new version) I get an error in wp-admin, and on the frontend. With the old versions, no problems.

    versions
    WooCommerce | 7.4.0 | 7.5.1
    WooCommerce Payments | 5.4.0 | 5.7.0
    Mollie Payments for WooCommerce | 7.3.4 | 7.3.6
    WooCommerce Subscriptions | 4.5.0 | 4.5.0

    error
    Warning: assert(): assert($billie instanceof PaymentMethodI) failed in /home/customer/www/sitename.nl/public_html/wp-content/plugins/mollie-payments-for-woocommerce/src/Gateway/GatewayModule.php on line 168

    Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/sitename.nl/public_html/wp-content/plugins/mollie-payments-for-woocommerce/src/Gateway/GatewayModule.php:168) in /home/customer/www/sitename.nl/public_html/wp-admin/includes/misc.php on line 1416

    Question

    What can I do to fix this?
    I have already cleared the cache (SiteGround Cache), but it doesn’t work.

    Hopefully someone knows, if more information is needed, please ask!
    Thanks!

    René

  • Hi Inpsyde Niklas the 7.3.7 test plugin works and removes the /Gateway/GatewayModule.php?on line?168 error

    it works for me, thank you so much!

    Thank you for your feedback. We have already released an update to address the issue. When you notice the official 7.3.7 update available, we recommend updating to this version. It is identical to the one linked earlier, but with a different version number.

    Just for some context, this warning only occurred when the connected Mollie account was not yet enabled for the new payment method. All our testing accounts were already enabled for the feature, so this slipped through testing.

    We apologize for any inconvenience this may have caused and appreciate your understanding.

    Kind regards,
    Niklas
