Hello,
I apologize for the inconvenience you are facing with Rank Math’s Table of Contents not reading the headings in your blog. If the TOC has stopped detecting the headings, please ensure that you have not excluded any headings from appearing in the table.
To check this, please follow these steps:
- Click on the Table of Contents block.
- Navigate to Settings.
- Head to Block → Settings → EXCLUDE HEADINGS and confirm that no headings are excluded from appearing in the table.
If you have verified that no headings are excluded and the issue persists, our team is aware of a bug that may cause higher-level headings to disappear when you add a lower-level heading before a higher-level one. We are actively working on resolving this issue in a future update.
In the meantime, you can monitor our changelog here for any updates related to this bug.
Thank you for bringing this to our attention, and we appreciate your patience as we work on resolving this issue.
If you need further assistance or have any other questions, please feel free to let us know.
