Installation

Installation of this plugin works like any other plugin out there. Either:

1. Upload and unpack the zip file to the '/wp-content/plugins/' directory
2. Activate the plugin through the 'Plugins' menu in WordPress

Or search for "View Admin As" via your plugins menu.

Minimum Requirements

• WordPress 4.1 or greater (Though I always recommend to update to the latest version!)

Install as a must-use plugin

Move the view-admin-as.php file into the root of your mu-plugins directory, not in the view-admin-as subdirectory.
This is a limitation of WordPress and probably won't change soon.

Example:
All files dir: /wp-content/mu-plugins/view-admin-as/...
Main file dir: /wp-content/mu-plugins/view-admin-as.php

Since 1.7.4: Or add a plugins loader script in your mu-plugins folder: Click here for an example
