Enabling this option partially overrides the previous option (the blocking of template=foo in the URL). If the template= URL query parameter specifies the name of a template which exists in your template directory, then it will be allowed without raising a security exception. This is required only on sites which are using more than one template at the same time. What we mean by that is that you can go to Joomla!'s back-end, go to Extensions, Templates and assign any of the installed templates to any number of menu items. When you do that, several core components –including com_mailto, powering the "send this page by email" icon in your articles– have to append template=yourDefaultTemplateName to the URL. This would cause your site to throw security exceptions whenever a legitimate visitor would, for example, try to send an article by email to a friend of his. By enabling this option you prevent this security exception from being raised.
