I have downloaded, enable and configure your plugin as indicated in the attachments. I have created three template override with Metro Rox and I want to use each of them for three different Joomla User Group. All the Joomla User ACL group are inherited from Registered group. Unfortunately template is not changing when I switch login from with different user from different user group.
Is it possible for you to upgrade Joomla, as you are not using a stable version of it?
