I created a new layout in Design Manager. I am admin on this site with full control.
In the SP designer 2013 I get: Server error: This file may not be moved, deleted, renamed, or otherwise edited.
I originally built was working in my sandbox editing the display of web-parts, now I want to mimic that under the main layout area. How do I get around this error to edit document? I can edit its corresponding HTML document.
thank you,
