Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Could you please check your browser console for script errors when you save your changes in your posts/pages?
If you see an error containing “updateMeta”, then your server must be blocking Rank Math’s API. Please refer to this guide to fix it: https://rankmath.com/kb/meta-data-not-saving/#firewall
Let us know how that goes. Looking forward to helping you.
Thanks! We contacted WPEngine to whitelist all Rank Math paths.
