Hi Nijiland,

This button text comes from WooCommerce. Please add the custom code below to change it. (How to add custom code? ↗):

add_filter( 'woocommerce_product_add_to_cart_text', function ( $text, $product ) {
	if ( $product->is_purchasable() && $product->is_in_stock() ) {
		if ( $product->is_type( 'variable' ) ) {
			$text = 'Select options';
		} else {
			$text = 'Add to cart';
		}
	} else {
		$text = 'Read more';
	}

	return $text;
}, 99, 2 );

You can change the text of the three states above as you want.
