Thank you for your reply.
There are more pagelayout.tpl and menu/flat_left.tpl, which are correct?
I modify files which path is \extension\ezwebin\design\ezwebin\templates, and can not see any changes on the web sit. Could you indicate the path to me? Thanks.
You'll want to be familiar with how templates get overridden (http://ez.no/doc/ez_publish/technical_manual/4_0/templates/the_template_override_system) and how to see which templates are being used (http://ez.no/doc/ez_publish/technical_manual/4_0/reference/configuration_files/site_ini/templatesettings/showusedtemplates). This knowledge will help you find which templates are being used and, if desired, develop a template to override one. Feel free to continue asking more specific questions as you go, and welcome to eZ Publish!
