/?gifts not working

[chac4l]

my page ?gifts is not rendering gifts.html.twig.
it only shows gift-header.html.twig.
i also found out there is another gifts.php on /gesior-shop-system/pages. slightly difference oon line 14, the file on gesior has
csrfProtect(); , when applied to my ''system'' gift page, it comes back with http500.

Any idea?

CODE gifts.php on html/system/pages:
`<?php
