Switch Blogger to “Classic” or “XML” Mode

Source

Many people still seem to be confused about how to apply new templates to their Blogger blog. It’s not suprising though because Blogger didn’t seem to care about clearly marking the differences between the two when you are at the template editor page in your control panel. They should have used a much better naming convention and put some type of heading on the editor page that CLEARLY says which mode your blog is running in. The fact is that Blogger can run in two different modes, one is called “classic” and the other is often referred to as either “XML” or “beta”. The confusing interface is what causes most of the problems when people try to paste in a new template, with complaints like “I can’t get it to work, I keep getting errors!”. This tutorial should help you to see the differences between the two modes and how to switch back and forth.
