OOPS!
You're missing a page.

In Admin > Blogs & Pages, create a page with the handle of this page with the addition of "-side" ex. If the page name is About Us then the handle is "about-us". If you create a page called "About Us Side" the the handle will be "about-us-side" and its content will appear here. If you use an image in this page make sure its width does not exceed 255px. Additionally make sure that the Shopify rich text editor does not add any unnecessary mark-up to your image or it may effect the way it is displayed.

The About Us page of your shop is vital because it’s where users go when first trying to determine a level of trust. Since trust is such an important part of selling online, it’s a good idea to give people a fair amount information about yourself and your shop. Here are a few things you should touch on:

  • Who you are
  • Why you sell the items you sell
  • Where you are located
  • How long you have been in business
  • How long you have been running your online shop
  • Who are the people on your team

To edit this information you can go to the Blogs & Pages Tab of the administration menu.
