How to create an "EDIT POST" page?

Been looking around for a plugin that functions in a way that users can edit their posts via front-end. No luck till now. I’ve bump into the front-end editor plugin but it only works for admins and users with admin capabilities. I’ve also tried activating WP Users plugin but it gets me an error that Header is Not Valid. It’s too bad since this plugin had shortcodes ready to use.

Any help on this one?
