- Steps provided to add a free theme and use Preview to test if the issue persists.
A second user reports the same issue on Dawn (a Shopify theme) after integrating with Facebook; older site versions and other themes display correctly. Their fix:
- Revert theme.css (the theme’s stylesheet) to a prior working version via Edit code > theme.css > “Current” dropdown > select an earlier timestamp.
- Remove the Facebook sales channel after domain verification.
Outcome/status:
- One user resolved the problem by reverting theme.css and removing the Facebook channel.
- The original poster has not yet confirmed a fix; the thread remains open, pending store details and testing on a fresh theme.
