Problem on Classic Editor

Hi, @satimis ???? Are you using a specific theme that includes that template, or is that a custom template created in the site editor?

Hi@ironprogrammer ,

No. I’m running Theme Twenty Eleven

Regards

Hmmm, Twenty Eleven doesn’t have a template named “Full Width” (Github repository search). The Classic Editor enables the old editing experience, but doesn’t change how classic themes expose templates (e.g. through the Template Name: file header).

As this doesn’t appear to be related to the Classic Editor plugin itself, I’ll close this topic for now. I would recommend searching the Twenty Eleven support forums if your issue relates to a customization of the theme (such as adding a new page template file).
