Safari keeps changing URL to "localhost"
Using my MacBook Pro I'm trying to get on a website, the website is "tumblrplug.com" but whenever I enter the URL and hit enter it just puts "localhost" in the search bar and says "Safari cant open page http://localhost/ because safari can't connect to the server: localhost" I don't really know what this means? All of my other websites (that I know) are working and this is the only one with a problem. It says the same thing when I'm trying to use my iPhone 4s, as well. This only started yesterday and I tried reseting safari and doing everything it said but nothing has worked.
MacBook Pro, Mac OS X (10.7.5)
