2 weeks ago, Google started being unable access my website anymore. In Webmaster Tools I can't fetch any pages, always getting error 403, and the website has been completely dropped from Google search results.
I can't figure why it suddenly can't see it anymore. I've checked .htaccess and there is nothing that blocks Google crawlers, and robots.txt is fine too.
The site is accessible normally for users.
Has anyone had this problem?
