Fatal error when calling available_variation()

Hello, I’ve encountered a fatal error in the current version of WPC Product Quantity Premium. The issue occurs in wpc-product-quantity.php around line 858: Fatal error: Uncaught Error: Call to a member function is_type() on false in /wp-content/plugins/wpc-product-quantity-premium/wpc-product-quantity.php:858 Stack trace: 0 /wp-content/plugins/wpc-product-quantity-premium/wpc-product-quantity.php(876): WPCleverWoopq->get_quantity() 1 /wp-content/plugins/wpc-product-quantity-premium/wpc-product-quantity.php(921): WPCleverWoopq->get_type() 2 /wp-content/plugins/wpc-product-quantity-premium/wpc-product-quantity.php(1850): WPCleverWoopq->get_min() 3 /wp-includes/class-wp-hook.php(324): WPCleverWoopq->available_variation() … The error happens when the method available_variation() is executed in a context where the $product parameter is false or null , so calling $product->is_type() throws a fatal error. The plugin assumes that $product is always an instance of WC_Product , but in some contexts (for example during certain AJAX calls or variation rendering), the woocommerce_available_variation filter can be triggered with an invalid or empty product reference. To prevent the fatal error, a simple instance check should be added before accessing $product methods, e.g.: if ( ! $product instanceof WC_Product ) { return $data; } Suggested fix: Add this validation in the following methods before using $product : get_type() get_min() available_variation() This ensures compatibility with all WooCommerce contexts and prevents fatal errors when $product is not properly initialized.
