Publish your store
Sign in to Store Editor and go to the Editor toolbar on your home page. If you use the Regular Editor toolbar and see the Publish Options button, you'll need to click it to publish your changes. If you've already published your changes, the Publish Options button will be faded and will read Published.
Note: If you use the Advanced Editor toolbar, the Publish Options button will always be visible and separate from the Published button. Learn more about publishing options.
Go to your published site and hold down the Shift key while clicking the Refresh or Reload button on your browser. This ensures that you are seeing the most recent version of your page, and not an older browser-cached version.
If you still don't see your changes, then you may need to publish again. Edit your site, go to the Variables page, and click Update. Then publish your site again.
