I've setup one of my projects under localhost, which is WAMP. I defined my deployment as "In place" and for the webserver URL I gave it "http://localhost". This works when I click the little browser icon at the top-right corner of the opened php file. It opens and runs the file in the browser under localhost.
However, when I open up the project and look under the Remote Host panel, it says "Server 'localhost' does not exist." I can still click the browser icon and run the file correctly on localhost, I just don't get it why the Remote Host panel says localhost does not exist?
