When click on blog post tag, I got 'Unknown action' error

[karimmtarek]

AbstractController::ActionNotFound (The action 'index' could not be found for Storytime::PostsController)

Same issue here, occasionally my app present the same error, mostly when the session is expired.

Besides that, I've not still understood why "show" was the name of the action used for both details and list views.
