Fatal error: integration with Facebook and Gift Cards (?)

[MyjoyVera]

Hi! Let's see if someone can help me, its the first time i write here and I have 0 idea of programing....

I'm using the PW Gift Card pluging in my store: myjoyvera.com
But as you can try yourself, when you try to add some of the gift cards into your basket ( https://myjoyvera.es/producto/tarjetas-regalo/tarjeta-de-regalo/)
It shows the following Fatal Error (see below),
I contacted the PW Gift Card team but they said me that the problem is the "woo-poly-integration" pluging, so this is why I ask here.

This is the error:

Hi, this plugin only provides a compatibility layer between the WooCommerce plugin itself and Polylang:

• This plugin does not provide a compatibility layer between PW Gift Card and Polylang
• This plugin does not provide a compatibility layer between WC_Facebookcommerce_EventsTracker and Polylang
• This plugin does not provide a compatibility layer between WC_Facebookcommerce_EventsTracker and PW Gift Card

Also when raising an issue please provide all the information requested on the template.

However, looking at your error log there, I can confirm that I am about to remove the function where the error seems to be happening - Hyyan\WPI\Cart->addToCartHandlerVariable and have left some instructions for temporarily commenting it out on issue #502 please check that issue

noted that on https://wordpress.org/support/topic/error-when-i-add-the-product-to-the-cart-2/
additional information is provided showing that two arguments should now be passed to apply_filters( 'woocommerce_add_to_cart_redirect', $url, $adding_to_cart )
nonetheless removing the code may be an even better solution
