Hello,
We apologize for the issue you are facing with saving drafts in the WordPress editor while using Rank Math. The error message you are encountering (403 Forbidden) indicates that there may be a restriction preventing access to the Rank Math REST API endpoint.
Here are a few steps you can take to troubleshoot this issue:
-
Check Firewall Settings: Since you mentioned that all security and caching plugins have been deactivated, it’s possible that your server’s firewall is blocking access to the Rank Math REST API. You can check if Rank Math is being blocked by your firewall and whitelist the following files if necessary:
/wp-json/rankmath/v1/updateMeta
/wp-json/rankmath/v1/updateSchemas
/wp-json/rankmath/v1/updateRedirection
/wp-json/rankmath/v1/getFeaturedImageId
/wp-json/rankmath/v1/getHead
-
Inspect Developer Tools Console: Open the Developer Tools Console in your browser and check for any additional error messages that might provide more context about the 403 error. You can do this by navigating to More Tools → Developer Tools and then clicking on the Console tab.

-
Check REST API Access: You can verify if the REST API route is accessible by visiting the following URL in your browser (replace example.com
with your domain):
`https://rankmath.com/kb/settings-not-saved/
If you see a notice that your access has been denied, it confirms that your site’s firewall is causing the issue.

-
Plugin Conflicts: Although you have deactivated other plugins, ensure that there are no conflicts with your theme or any custom code that might be affecting the functionality of Rank Math.
