A blocking robot.txt file in the top folder of a web server stops a robot like Google, which analyzes pages, from continuing. As a result, the search results are not refreshed;
To authorize for Google Search, you may need to re-register the web domain; just to clean up search results;
– Have in .htaccess: Header always set X-Robots-Tag “noindex, nofollow”; – Unblock in robots.txt not to block analysis : ‘User-agent: *’ and then ‘Disallow:’ with no details fits; – Log in to Google Search to have search results cleaned up.
A rewrite in the .htaccess file, or a 301/302 redirect, to another web domain, may affect search results.
