Hello,
We apologize for the issue you are facing with saving your SEO data in Rank Math. There are a few common reasons why this might happen:
1. Plugin Conflicts
There could be conflicts with other plugins that prevent Rank Math from saving the SEO Title, Description, and Focus Keyword. You can check for plugin conflicts by following our guide on plugin conflict.
2. JavaScript-Related Errors
JavaScript errors can also cause issues when saving metadata. You can diagnose these errors using the JavaScript Console in your browser. Here’s how to check for JavaScript errors in Chrome:
Open the Developer Tools Console Panel
- Navigate to More Tools → Developer Tools from the Chrome menu.

- Click the Console tab.

- If you see any errors, note them down as they may indicate what is causing the issue.
3. Firewall Blocked Access to the File
If you are using a firewall, it might be blocking Rank Math from saving data. Check if Rank Math is being blocked and whitelist it if necessary. Look for blocked access to these files:
/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
You can use Wordfence in Learning Mode to whitelist these files.
If you have checked these potential issues and are still experiencing problems, please reply to this ticket with any error details you find, and a human agent from the Rank Math Support team will assist you further.
Thank you for raising this concern!

Hello,
The Sucuri firewall is blocking access to the REST API route used to update the metadata. Please refer to the screenshot in the sensitive data section.
We would recommend getting in touch with their support team and asking them how you can go about whitelisting that route mentioned in the screenshot URL.
Looing forward to helping you.
kindly assist me in resolving the problem
Hello,
You may need to get in touch with your web host and ask to whitelist this route in their Sucuri firewall:
/wp-json/rankmath/v1/updateMeta
The issue should be fixed once the route is added to their whitelist.
Looking forward to helping you.
