Updates keep Ghost secure and add features. Occasionally a theme or custom snippet disagrees with a new version. A calm checklist gets you back online faster than random Googling.
Symptoms and first checks
| Blank or partial page | Check Ghost error logs; disable recent Code Injection blocks one at a time. |
| Styles look wrong | Hard refresh; purge CDN or host cache; confirm the active theme is the one you expect. |
| Custom routes 404 | Open routes.yaml in Admin; validate indentation and upload again. |
| Portal or members broken | Verify Stripe keys, domain URLs, and that the theme does not override critical links. |
Isolate the theme
- Switch temporarily to Casper (or another stock theme).
- If the issue disappears, the problem is likely in your custom or third-party theme.
- Reactivate your theme and note the exact template (home, post, tag, page).
