    Hi team,

    We try to update our WordPress / WooCommerce to php8. When we put a product in the cart it displays the following error (replaced the domain with xxx)

    Do you have an update / solution for this?

    Thanks,

    Coen

    Hey Coen,

    Please update to version 3.9.4 (just released) and let us know if everything is sorted now.

    Hi Omar,

    If I change

    $_product_qty_step = $product_qty_step;

    into

    $_product_qty_step = (int) $product_qty_step;

    on rule 2911 in class-alg-wc-pq-core.php

    …the error is gone and it seems to work in php 8.0 on our configuration. The value $product_qty_step was empty btw.

    Can we add this?

    Thanks,
    Coen
