Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I have just tried to log in with those credentials but they seem to don’t be working, could you check them?
Looking forward to helping you. Thank you.

Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
After checking it, it seems you get the following errors when trying to save:
api-fetch.min.js:2 POST https://website.com/wp-json/rankmath/v1/updateMeta?_locale=user 403
post.php:1 Uncaught (in promise) {code: "invalid_json", message: "The response is not a valid JSON response."}
Those errors usually are caused when something is blocking access to the WordPress API REST.
Since you already tried for plugin conflicts and even with everything disabled, it still doesn’t work, I would recommend contacting your hosting support, to check if something is blocking the WordPress API REST.
Please let us know if you find the culprit.
Looking forward to helping you.
