Dear, Gewoonbovenaan,
Price by Formula Calculator for WooCommerce plugin – is causing an issue for AJAX adding to the cart even from the shop page.
PixelYourSite plugin – gives js error and causes the issue for adding to cart from the Wishlist page.
At this time, we can only offer two solutions:
1. Deactivate the PixelYourSite plugin;
2. Hide the button for adding all products using custom CSS code:
.form-actions .add-all-products {
display: none;
}We will consider the possibility of fixing the PixelYourSite plugin as it causes errors when adding all products from the wishlist, we will let you know if it can be solved.
Kind Regards,
8theme team
