How can I increase the number of default product variations in WooCommerce?
A WooCommerce variable product is a standard product type which allows you to offer a group of variations (different sizes, colors, prices and so on) in a product to your customer. This simply means that it shows a wider array of attributes which your customers can choose from.
In order to modify this setting, SSH into the server and open your functions.php file located here:
/wp-content/themes/YOUR_THEME/functions.php
Now, let’s modify the variable:
Constant – WC_MAX_LINKED_VARIATIONS
vs
Filter – woocommerce_ajax_variation_threshold
