Not seeing the template info? In the WordPress admin area, under Users, find the entry for the administrative login you are using. Click the edit link. Look for a checkbox named Toolbar. Make sure that is checked/enabled and the setting is saved (Update Profile). You should now see the template info, assuming you are visiting the site with the same browser you used to log into the sites's WordPress admin. You can do this by having different tabs open in the browser. This is not mentioned in the plugin FAQ. Otherwise, this plugin displays the template information as advertised. It can be very useful for tracking down obscure PHP problems inside template files.

A very helpful plugin.

Nice and simple, does the job, no fuss. Thank you JOTAKI!

This plugin is useful to make theme and customize theme.

this is a mandatory plugin for me, i develop all my themes with it and i don't wanna live without it ❤️

If you want to edit any theme, then you should get this plugin. It shows you which template file is used for the page you are watching. That way you will always know what template file to edit in your child theme. Great and thanks a lot!
