I'm having a strange problem with my main site. Google webmaster has started reporting that the site has "Severe health problems" because a page is being blocked from the crawlers. The page is Code: http://mysite.com/wp-admin/ Which is the wordpress admin area and is meant to be dropped. I had 1st place for a 27,000 search and a few 2nd page for bigger searches. All have since dropped out of the rankings completely and are not visible in the top 100. Ive slowly started getting them to reappear. I think the dropped rankings and the "severe health" notice are related because i have not seen a drop in other rankings i have. Any idea how to fix this or has anybody seen this before?
