Confusing tab order
DOM order matches layout
Duplicate IDs and broken ARIA relationships confuse assistive tech when it resolves references.
Where this comes from on WordPress
Themes, plugins, and block output—fix the template or block once so every page using it improves.
What this issue means
Fix
Rename duplicates; generate stable unique ids for lists rendered in loops.
How to fix on WordPress
In WordPress, fix the underlying theme or block output: child themes, block patterns, or plugin markup. Re-scan after updates—page builders often regress heading order or button names.
How to fix
Ensure ids are unique per document; generate stable unique ids in lists.
Fix templates so duplicated components do not reuse hard-coded ids.
Common mistakes on WordPress
- Fixing only one page while the pattern lives in a shared template.
- Caching plugins serving old HTML after fixes.
How to verify the fix
- In wp-admin, open the page on the front-end; use keyboard only through the fixed region.
- If you use a builder, re-publish/clear cache so changes appear.
- Rerun the public scan on the same URL and compare the report link.
