routing errors all the time ,cant get past the welcome sign running on rails .
in win7 and ubuntu systems
latest gems and ruby of course .
tried everything i can think of using all the books and online material.
nothing past localhost:3000 seems to work ,i just get the routing error despite checking all the code with the examples .
application controllers look ok ,apps files ok, .erb files ok .route files ok ,public index file deleted
i have plowed thru all the relevant book examples cross checking them to find an error but i cant .
