I have some problem after deploying my application Rails 4 with Heroku. The application works very well in development, but it doesn't work totally in production. Some pages don't appear (Show) = white page, in particular for the pages which have a database. I think i have some problem with Sqlite3 and/or postgresql but i don't have to resolve the problem. Please help me.
