So I don't know if this is a bug or a feature but I wanted to replace the Gift Wrapping option with a custom one, and for that I want the gift message text removed. Everything works and the gift message disappeared after I commented out the following part in the order-carrier.tlp file:
<p id="gift_div">
<label for="gift_message">{l s='If you\'d like, you can add a note to the gift:'}</label>
<textarea rows="2" cols="120" id="gift_message" class="form-control" name="gift_message">{$cart->gift_message|escape:'html':'UTF-8'}</textarea>
</p>
However, now I have the issue that it gives me the error "Invalid gift message" even though I removed the message field which is strange, because it shouldn't be a mandatory thing. Or at least it wasn't mandatory in PS 1.6.
Does anyone know how to fix this?
