saving woocommerce options

hi

first, very good and simple plugin, which makes it easy to integrate. congratulations.

now, I have found that when the plugin is active, the pmatc_sanitize_ajax_cart_settings() function is executed for any saving of woocommerce settings. as a result, changes in woocommerce settings are not saved (I think since version 9.6.0). for example, in woocommerce > settings > general, activating taxes checkbox, after saving, when the page is reloaded, the checkbox is still deactivated.

I’ve solved it for now by adding if (strpos($option[‘id’], ‘pmatc_ajax_cart_’) === 0) { just before the switch ($option['id']) {... .

edit:
another better way can be change this add_filter('woocommerce_admin_settings_sanitize_option', 'pmatc_sanitize_ajax_cart_settings', 10, 3) for this:

add_action('woocommerce_settings_tabs_pmatc_ajax_cart', 'pmatc_register_sanitize_filter');
function pmatc_register_sanitize_filter() {
    add_filter('woocommerce_admin_settings_sanitize_option', 'pmatc_sanitize_ajax_cart_settings', 10, 3);
}

I hope you can fix it in future updates.

many thanks
