Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to this issue.

We found that your Wordfence security plugin is blocking access to Rank Math’s files.

You need to whitelist Rank Math and its files in your firewall or security plugin settings.
Please follow this guide to whitelist Rank Math in Wordfence: https://rankmath.com/kb/whitelist-rank-math-in-wordfence/

We hope these steps help you solve the problem. If you still can’t save your SEO Title on your site, please let us know. We’re always happy to help.

Thanks.
