I need to change submit button text. I am using CartFlows plugin on WordPress with Woocommerce. In CartFlows setting I can add "custom text on place order button" but it does not work. It shows but when page is fully loaded then it disappears and text is default again. Code of button: <button type="submit" class="button alt" name="woocommerce_checkout_place_order" id="place_order" value="Kupuję i przyciągam obfitość!" data-value="Kupuję i przyciągam obfitość!">Zapłać</button> As you can see value should be "Kupuję..." but it shows as "Zapłać". I tried using the following code in functions.php: add_filter( 'woocommerce_checkout_place_order', 'wc_custom_order_button_text' ); function wc_custom_order_button_text() return __( 'Place Donation', 'woocommerce' ); } but it does not work. How can I solve this?
