I'm using my own computer, running Mac OS X 10.8, as a testing server for a site I'm working on. This isn't the first time I've done this, and so far it's worked pretty much without a hitch.
But recently, for seemingly no reason, after I put my files to the testing folder via Dreamweaver, no browser can connect to localhost. I've tried going into Dreamweaver's Manage Site dialog, and deleting and re-adding the server, and restarting my machine, to no effect. What can I do to remedy this?
