Rails application getting 500 error page on production -

-

i'm migrating working rails 3 application server type of service. firstly had issues static files (e.g. application.css, application.js) not being rendered (404 status). resolved issue turning config.assets.enabled true.

now i'm having problem of error 500 no matter go in application. assume it's asset problem. don't error in log/production. follow:

started "/" 187.39.38.147 @ 2016-06-14 12:33:05 +0000 processing bookscontroller#index html   rendered myapp/layouts/500.html (0.7ms) completed 404 not found in 16ms (views: 10.0ms | activerecord: 1.9ms)

i have no idea of how find out what's wrong fix that. can find out what's wrong ?
