Hello @wandex,
Thank you for contacting Rank Math and bringing your concern to our attention.
This situation usually happens when there’s a problem with the file’s permissions or location on the server.
Please contact your hosting provider for assistance. They should be able to help you resolve the issue and grant the necessary permissions to the robots.txt file so that search engines can crawl your website.
You can also check the file path to ensure that it’s in the correct location and that the file name is written correctly as “robots.txt”.
If an actual robots.txt file is present in the root folder of your site, the option to edit the file from Rank Math > General Settings > Edit robots.txt won’t be available.
Please delete it from the root folder and edit it from the Rank Math Plugin if required.
Learn more about robots.txt here:

We hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
