There are coding changes in the gift_card.liquid file for my Shopify store

Somehow the coding to the gift_card.liguid file has been changed. Now, customers can no longer access the Gift Card link on my front page. Any help is greatly appreciated because I know nothing about HTML coding.

Under the Recent changes heading there is a drop down menu if you click on Current, here it will have an historical list of snapshots from previous saves you can revert back to.

Hope this helps
