functions.php

	return 10;
}

add_filter( 'woocommerce_ajax_variation_threshold', 'custom_wc_ajax_variation_threshold', 10, 2 );

Hello Claudio,

Thank you for sharing this useful snippet - way better than the standard approach.
Do you know if there is a way to have Amazon's behavior instead?

So instead of showing "Sorry, no products matched your selection. Please choose a different combination.", to have the option to see the available options:

Here's the listing I am referring to:
https://www.amazon.com/OULUOQI-Stainless-Magnetic-Replacement-iWatch/dp/B099JF5S9Z/
Thank you!

Regards,
John

Product page is not loading after making changes to the product variation

The product page is not saving after i make changes to the product variation. I have more than 100 variations
I have attached a video. The cache has been cleared and the issue is still the same.

It worked correctly for 100 variations.
To be cautious and not to touch the "functions.php" file, I inserted this code through the WP Code plugin.

Thank you very much!
