How do I force the header that I am attempting to work on to display within the Cornerstone editor on the page it is assigned to (the page also has that specific header selected as its header).
Currently the system defaults to trying to display the header within the context of the main page for the site as per WordPress Setting, under Reading. Resulting in the following error popup and the inability to see the header and thus edit or work with the editor.
I have cleared the cache for the site, cleared the cache for the browser, used a different browser.
