Hello,
Thank you for reaching out about the warning message you are encountering with the Rank Math plugin after adding Journey with the Grow plugin. The warning message "Warning: Undefined array key ‘titleWrapper’ in /home/customer/www/eatseerv.com/public_html/wp-content/plugins/seo-by-rank-math/includes/modules/schema/blocks/toc/class-block-toc.php on line 103" seems to be related to a conflict between the plugins.
To resolve this issue, you can follow these steps:
-
Update Rank Math: Ensure that you are using the latest version of the Rank Math plugin. Updating to the latest version can often resolve compatibility issues with other plugins.
-
Clear Cache: After updating Rank Math, clear all caches, including any server-side caching, to ensure that the changes take effect.
If the issue persists after following these steps, you may need to debug the specific conflict between Journey, Grow, and Rank Math. In such cases, it’s recommended to reach out to the support team for further assistance. You can assign this ticket to a human agent by clicking on the appropriate button.
Thank you for your understanding, and we are here to assist you further if needed.

Thank you, I have cleared the cache and updated both plugins. I even de-activated them and re-activated then cleared the cache again and am still getting the same error message.
Hello,
We released a quick Beta update you can try to see if that helps.
Please enable the Beta update by following this:
https://rankmath.com/kb/version-control/#beta-updates

If you are unable to see an update, please clear Rank Math’s transients from:
WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients > Remove transients

Please clear the caches, server, and WordPress after updating.
You can disable the Beta updates once you update to the latest version and if the issue is fixed.
