Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
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/
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.

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/
Please do take a complete backup of your website before sharing the information with us.
We really look forward to helping you.
Hello,
I have updated the sensitive data as requested. Can you please check further?
Thank you.
Hello,
Thank you for the follow-up.
I’ve checked your site, and it seems that the Nofollow External Links option is disabled.

The Nofollow Domains only works when that option is enabled. Now your external links already have the nofollow tag.
I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.

Hello,
Thanks for getting back.
Rank Math doesn’t add any rel tags if a rel-tag is used on an individual link. We do that so users can still selectively nofollow or dofollow a link. I checked and the image already has a rel-tag added to it therefore Rank Math is not adding nofollow to it.
And as the video is inserted inside an iframe it’s not considered as an external link and that’s why Rank Math isn’t making it nofollow.
Hope this helps. Let us know if you need any further assistance.
Thanks for your all help. I didn’t imagine I would get so much help from you guys being a free user.
RankMath Rockzz 😀
