Why can't I start my A/B test?

Fix the messages you can see when creating or starting a test, from a greyed out button to theme and permission errors.

Updated November 4, 2026

A test needs Plus, a live bundle or cart, the widget in your live theme, and Shopify's analytics permission. If one is missing, the test stays a draft and you see The test is still a draft with the reason.

Messages and fixes

  • "A/B testing is included with Plus." Start Plus or your trial. See How to subscribe to Plus.
  • "Publish this Bundle before starting this A/B test." Open the bundle and click Publish.
  • "Enable the Cart Drawer before starting this A/B test." Turn the cart on in the app.
  • "Add the Section Store Bundle app block to a product template in your live theme before starting this A/B test." Click Turn on in theme on the Bundles page, then Save in the theme editor. The Bundles app embed counts. So does the block.
  • "Turn on the Section Store Cart app embed in your live theme before starting this A/B test." Turn on the Cart drawer app embed in the theme editor, then click Save.
  • "Shopify could not confirm the setup in your live theme." Check that the embed is on, then try again in a minute.
  • "Grant Shopify analytics and paid-order permissions before starting this test." Reload the test and approve the Permission Required window.
  • "Version traffic must total 100%." Fix the split, or click Split evenly, then Save traffic.
  • "The combined discount configuration exceeds Shopify's 10,000-byte limit." Your versions hold too many discounts or reward tiers together. Remove a version, or remove some offers.
