Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
I’ve checked your site and upon further inspection, I noticed that you have enabled the option “Discourage search engines from indexing this site” on your reading setting, this is why its overwriting your robot settings.
It looks like this is a development site so once you’re about to push this to production site, you would need to remember to untick that option so the noindex option would not be overwritten.
Additionally, I’ve checked your global meta setting and you’ve also set this to no-index, you can change this setting once you have disabled the option above.
Please see screenshot below:
– WP search engine visibility setting:

– Global Meta option set to no-index:

I hope that helps, let us know if you need help with anything else.
Looking forward to helping you. Thank you.
Hey Febby!
You’re right. I updated this setting on my site & it worked. Thanks for a quick response. Appreciate it! Thank you so much for your help.
