Focus Keyword field won’t add the focus keyword

Hello,

Thank you for contacting Rank Math, and sorry for any inconvenience caused.

Please check if you are using a Firewall, as it may prevent saving the changes.

If you are using a Firewall, please whitelist this route:
/wp-json/rankmath/v1/updateMeta

Whitelisting the route should fix the issue.

I hope this helps. Looking forward to helping you.

Hello,

Please take a backup of your .htaccess file and replace it with the default WordPress .htaccess file. You can get the file here: https://wordpress.org/support/article/htaccess/

You can follow this guide to edit the .htaccess file:

If the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

https://wordpress.org/plugins/temporary-login-without-password/

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.

Hello,

I logged in to your website and checked the settings.

I was unable to replicate the issue, the focus keyword is added and saved without any issues and the SEO Analysis is also updated.

I have added the focus keyword on the latest post, if the issue is on some specific post, please share the affected URL with us so we can check.

We look forward to helping you.
