Dashcode localhost server fails

I write a dashcode program and run it to test. this should connect to http://localhost:50853/index.html but fails to do so with a "coul开发者_开发技巧d not connect to the server". THis worked some months ago when i was last working on it but have done several update since then. Also i cannot see anywhere to tweek this address. looks as though it is fixed.

Make sure your /etc/hosts has a line like this.

127.0.0.1 localhost

This fixed my problem.
