Error with PHP 8

  • Hello,

    I’m getting this PHP error when using PHP 8:

    CRITICAL Uncaught TypeError: in_array(): Argument #2 ($haystack) must be of type array, string given in /home/*******/wp-content/plugins/gift-products-for-woocommerce/front/wg-frontend.php:637

    On PHP 7.4 it works fine.
