With this plugin you can hide text in your articles with a password or from specified user groups with a simple syntax call directly in the articles. Special features are the unusual syntax use (square brackets) and the Safe Mode to avoid hidden text to be showed in other components (e.g. search component). Because the typical plugin syntax is removed in calls from the outside, the plugin does not use curly brackets. In the Safe Mode the whole article is replaced with an empty string if ECR detects a call from outside the content component of an article which uses the plugin.
Install the plugin in the backend, then adjust and publish it in Extensions -> Plugins -> Content - ECR - Easy Content Restriction.
