Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please share your website URL and the specific URL where you are experiencing the issue with the ‘noindex’ tag.
To further troubleshoot this issue, please check the Search Engine Visibility settings in WordPress. Please go to WordPress Dashboard > Settings > Reading and ensure that the checkbox labeled ‘Discourage search engines from indexing this site’ is unchecked, as shown in the screenshot below:

Meanwhile, you can try to follow this guideline and see if that works for you: https://rankmath.com/kb/error-submitted-url-marked-noindex/
Let us know how it goes. Looking forward to helping you.
Thank you.
Nope! Already did everything from common sense fixes like this to every suggestion from your forum to watching any video you have available about the subject. Nothing works….
Well aside from going into cPanel and deleting CSS assets from your plugin. That worked. Obviously this is an issue many are having and you guys are ignoring. I will be making it a point to bother you guys until you resolve this.
Thank you.
Hello,
This tag you mentioned is shown when you are logged in to your website admin.
You’ll notice at the WP Admin top bar when you are viewing any page of your website, that there is a Rank Math icon that provides shortcuts to options available in the Rank Math settings and tools.
Part of the shortcut available is the option to quickly mark or set the page you are viewing as “No Index” or “No follow” as shown in the image below:

What you see when you are viewing the source code of your webpage is the HTML output of the wp Admin top bar.
This does not set the webpage or your entire website with the ‘noindex’ or ‘nofollow’ tag.
You can view your website or the webpage in incognito mode or view the page when you have signed out of your WordPress dashboard to confirm this.
Hope this clarifies the issue for you and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
Yup! Tried that too! The only thing that worked was deleting your CSS assets in cPanel.
