With the rise of secure websites we need an easy way of replacing all the http links with its secured version. With this plugin you only have to install and activate it and it replaces all the protocols on-the-fly. It doesn’t modify the database or theme contents in any way. This plugin tries to facilitate the transition from an unsecure site to a secure version of the site.

This plugin modify the protocol of all links by its protocol-less counterparts.
