Hi there.
When I make a simple search at Google (Brazil) to find my blog, it only appears the following link:
http://blog.vigilanti.com.br/wp-login.php?action=lostpassword
I've tried to generate a robots.txt file with the content below to solve the problem...
User-agent: *
Disallow: /wp-
...but there's no way to upload a new robots.txt into the server! So, what should I do to make Google bots don't find /wp- pages on my blog anymore?
