问题描述:

I returned to my first hello world Rails program from Hartyl tutorial and I tried to run the application which had previously worked perfectly and displayed 'Hello World'. This time it doesn't run and when I go to Share and try to open the url, it says it couldn't find the application.

Any ideas why this would happen? I tried to run the rails server command from scratch and went back over the instructions but hasn't solved it.

Would appreciate any help and your patience, thanks.

*Wish I could give more info. This is the first program I've done in Rails and first time I've returned to a program after a mini hiatus in Rails so I expected it to run as it did before when I returned to the Cloud9 IDE that the tutorial uses. In general, should this just run as it did before, or is it normal that you have to start back in the terminal again to see it running in the url?
