He is basically saying that you have some cache in place where the name is outputed.
Could be cache-block, a template (.tpl) block that makes sure dynamic templates are cached to static html to not have to re generate the block on every request (to improve performance).
You can debug templates by enabling site.ini [TemplateSettings]ShowUsedTemplates=enabled & DevelopmentMode=enabled and other settings. Take a look on doc.ez.no to see how to work with ini files and overriding them, and to see the different settings you have available in site.ini.
