It is not a good idea to post an image, just copy/paste the important
text here. It is even worse if you just post html into a text email
so that the image does not even appear. Have a look in
development.log first though, often there is useful information there.
Also do the rake messages you posted work ok?
You say you get the error when you run the app, what do you mean by 'run' it?
