When I try to run my Ruby on Rails app it shows the error page I tried rake db:drop rake db:create rake db:migrate rake db:seed still the problem persists how can I fix this issue

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?
