YouDu CMS uses a template that has been marked as a system template to display system messages such as 'Page not Found', 'Restricted Access' and 'System Error Messages'. Any page template can be used as a system template as this is set when a template is added or edited (see 'Editing Templates' for details). When the CMS displays a system template it replaces the placeholder

<div id="containermisc1"><!-- c_misc1 --></div>

with the system message. All modules except for the following are removed when displaying a system template: HTML, Headline, User Login, Search Box, External Links.
