jHackGuard Support Page
jHackGuard is a security solution for Joomla developed by SiteGround. It protects your website by filtering the data from the users' input and implements additional PHP security settings. At the same time the plugin is disabled for the authenticated administrators so that its filters don't prevent them doing administrative tasks.
Check out the official jHackGuard page for more information on how to configure and use the extension.
In case you have issues with the plugin, please reach our support representatives from your User Area.
