The theme appears to be pulling information from Advanced Custom Fields that have been added to a page or post with the ID of 18.
If you’re not sure which page has the ID of 18, you can find it by editing any other page, and then changing the URL. The URL will be something like /wp-admin/post.php?post=52&action=edit. You just need to change 52 (or whatever ID you see) with 18 to edit that page. You should see fields for that info there.
@jakept That worked! Thanks so much 🙂
