Lock Out Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
This plugin will allow you to put your website into Lock Out mode to prevent access while you preform upgrades or maintenance on your site. Includes the ability to upload a pre-made html file for use as a placeholder page while in lock out mode or build your own online. The login page is still accessible and will allow only the user role you set to view the site normally while in lock out mode.
