Does anyone have a clue of where to start to correct and get back to cornerstone loading properly to edit the page?

Thanks.

Hi There,

Thanks for the details!

I can see your setup having an older version of WordPress(version 4.8).

Please update your WordPress for a possible fix.

Please take a backup before updating the site to avoid any damage.

Thanks.
