I recently tried to install Widgetz's detail.cgi, to show the detail pages on the fly, but from some reason, when i'm enter detail.cgi?id=xxx, It's tell me about an Unknown tag for the basic tags (like id, title, etc.).

What should i do to present the Detailed Pages correctly?

P.s the same tags shown correctly when i use the Basic build_Detail option, based on the same template file.
