Avada updates can be safe for one site and risky for another because child theme overrides, copied templates, custom hooks, and dynamic CSS rules change how the live site behaves. A diff checklist finds the risky files before production sees the update.
Use this when an Avada site has a child theme, custom header, layout builder templates, copied template files, custom functions, mobile menu changes, form styling, or CSS generated through Avada options.
Quick answer
Avada Child Theme Override Diff Checklist should be handled with a narrow evidence-first workflow: list overrides, diff templates, patch staging, then verify the result before making broader changes.
What to check first
- List child theme templates, functions, shortcodes, custom CSS, and Avada layout overrides before updating.
- Compare override files against the current parent theme or builder version on staging.
- Check headers, mobile menus, global layouts, forms, checkout pages, and landing pages that use custom templates.
- Regenerate Avada dynamic CSS and capture before and after screenshots for the same URLs.
- Keep a rollback plan that names the exact file, theme version, and option export used before the update.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
|---|
| List overrides | List child theme templates, functions, shortcodes, custom CSS, and Avada layout overrides before updating. | Every override file has an owner, purpose, and current compatibility note. |
| Diff templates | Compare override files against the current parent theme or builder version on staging. | Header, menu, form, checkout, and landing page screenshots are captured before and after. |
| Patch staging | Check headers, mobile menus, global layouts, forms, checkout pages, and landing pages that use custom templates. | Dynamic CSS is regenerated only after file-level risks are reviewed. |
| Regenerate CSS | Regenerate Avada dynamic CSS and capture before and after screenshots for the same URLs. | The rollback plan names the exact files and option export to restore. |
Why this usually happens
- A child theme can keep an old template structure after the parent theme changes.
- Dynamic CSS can make a broken override look like a cache issue.
- Global headers and layouts often hide custom PHP, CSS, or shortcode behavior.
- A file diff catches risks that a plugin update screen cannot see.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
find wp-content/themes/Avada-Child -type f | sort > /tmp/avada-child-files.txt
diff -ru wp-content/themes/Avada/templates wp-content/themes/Avada-Child/templates > /tmp/avada-template-diff.txt
# Review changed templates before updating production.
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- List overrides
- Diff templates
- Patch staging
- Regenerate CSS
- Approve rollback
What to tell the client or owner
Tell the client which override files were safe, which were changed, and which should be removed or rebuilt.
Production verification checklist
- Every override file has an owner, purpose, and current compatibility note.
- Header, menu, form, checkout, and landing page screenshots are captured before and after.
- Dynamic CSS is regenerated only after file-level risks are reviewed.
- The rollback plan names the exact files and option export to restore.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
