This plugin adds the name and path of the theme (template) file used to generate the html page into the page’s source as a comment. It will also add the name of the header, footer and sidebar if they are included.
This is useful for debugging and seeing what template file generated a page.
To use, activate, then reload any open pages. In the HTML comments, you can search for “TEMPLATE INFO” to see the added comments with the names of the template files included.
