Your store URL is available to access, except for the gift card page. If you feel uncertain why the gift card is not showing correctly, you can also further test if it is working under incognito mode page, and you can get the real feedback as well, a kind reminder here!
I have double-checked the page content on this URL specifically, as when I attempt to access it, there is no content so far. You may need to verify if the page content is redirected properly. Thank you!
