I made some edits to my live site this morning, including a color theme change. All looks great in the editor, but preview now comes up blank -- and so does going to the URL directly.
I'm in the process of creating a sandbox so I can restore a system backup from earlier today. (I do have a copy of the site in a developer environment -- but that version was built in non-enhanced data model, the production environment is enhanced-model, so I can't use a solution to move it over...)
But...any ideas why that happened? Other things to try to remedy?
(scolding for touching the live site directly cheerfully accepted)
thx
