Hello,
Thanks for contacting us and we regret the inconvenience caused!
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.
To determine that, please follow this troubleshooting guide:
https://rankmath.com/kb/check-plugin-conflicts/
Please let us know if you find the culprit.
Only the site admin would know and your users won’t be affected by this troubleshooting.
Looking forward to helping you.
Thanks!

Hello,
Thanks for getting back to us.
Could you please confirm whether you performed the plugin-theme conflict test that I suggested to you above in this ticket? If yes, then please tell us what was the outcome of the test.
If that doesn’t help, then 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.

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):
https://wordpress.org/plugins/wp-security-audit-log/
We really look forward to helping you.
i think, these is a validation problem.
please tell me which file to check send directory path
Hello,
Thank you for the follow-up, and sorry for the delay.
The advanced robots meta snippet value is used to modify the number of characters for the snippets provided by the plugin. -1 is the default value, which means that the snippet entered in the plugin will be displayed as it is. It also means “No-limit” when counting elements.
Could you please also check on your WordPress dashboard > Rank Math > Titles & Meta > Global Meta and check the default Advanced Robots Meta?

And in default Post Advanced Robots Meta

If the issue still persists, please follow the instructions provided by my colleague above to further investigate this issue.
I hope that helps. Thank you, and looking forward to your update.
