im with Crazy Domains and yeah last night same issue as everyone here…
Im having the same issue, there is no error warning, the backend of WordPress or site.com/wp-admin has broken.
So the normally left sided menu is creating a fullwidth menu and every button is displayed in simple text. It has become a basic text .html looking thing. So its one long page with no columns.
Hard to explain, but that picture gives you an idea of whats happened to the menu…
