Well, I tried to enter my robot.txt file page but all I get are the three lines with User-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/ .
To add the address http://www.YourDomainName.tld/sitemap_index.xml
or
http://YourDomainName.tld/sitemap_index.xml
as suggested, it will not allow me. I can read the file, but cannot enter either of those two address at all.
I’m going crazy too! Googlebot says it cannot crawl my website anymore…so if wordpress won’t let me alter my file, what can I do??
