Hello,
We apologize for the issue you are facing with saving configuration information across your websites. It sounds like there may be a few reasons why the metadata isn’t being saved on all three sites.
Here are some steps you can take to troubleshoot this issue:
-
Check for JavaScript Errors: Open the Developer Tools Console in your browser (you can do this by pressing Ctrl + Shift + J
on Windows or Cmd + Option + J
on Mac) and look for any errors that might indicate a conflict with other plugins or themes. If you see any errors, it could be causing Rank Math not to save the metadata. You can refer to the following image for guidance:

-
Firewall Settings: If you are using a firewall, it might be blocking access to Rank Math’s files. Ensure that Rank Math is whitelisted in your firewall settings. You can check 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
-
Page Rules in Cloudflare: If you are using Cloudflare, you may need to create page rules to disable security for the Rank Math files. This can help ensure that the data is saved correctly. You can follow the instructions provided in this image:

-
Plugin Conflicts: Sometimes, other plugins can conflict with Rank Math. Try deactivating other plugins one by one to see if that resolves the issue.
If you continue to experience problems after trying these steps, please reply to this ticket with the URLs of the websites where you’re having issues, and a human agent from our support team will assist you further.
