Installing through WordPress
Restrict Content Pro is installed just like any other plugin in WordPress.
Once you have downloaded the .zip file from your purchase receipt, log into your WordPress site and click on Plugins > Add New. At the top of the screen is a button titled Upload Plugin. Click this.
You will now be asked to select a file from your computer. Navigate to where you saved the .zip file from your purchase receipt and select it.
Once installed, click Activate Plugin.
You will now have a menu item label Restrict near the bottom of the admin menu in WordPress.
You will also be presented with a notice that says you should configure the Restrict Content Pro settings. Click this link and proceed to Setting Up Restrict Content Pro.
