Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
It seems to be working fine on our end.
Assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
Only the site admin would know and your users won’t be affected by this troubleshooting.
If the issue persists, please record a video screencast using a tool like Loom showing the troubleshooting and 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:
Can you please check if you have any firewall that may be blocking our API route preventing you to save the changes? You may refer to our guide here: https://rankmath.com/kb/meta-data-not-saving/
We would like to further check the issue, however, the login information you shared doesn’t seem to work.
Can you please verify so we can debug the issue further?
Can you please tell us the changes you made? Did you ask your hosting team to whitelist the endpoints I mentioned in my previous reply? From what I see, the upateMeta endpoint is still getting blocked by the server and it shows a 403 error.
