My apologies, it appears that the issues I was seeing were because Enfold was out of date. Kept FTP’ing the wrong, earlier version rather than the most recent version. Things appear fine now, so far as I can tell.
Seeing a lot of issues myself after accidentally updating to 4.1 (thought it was 4.01). Page and post builders break, and the console throws these errors:
Uncaught TypeError: Cannot read property 'hasClass' of undefinedload-scripts.php:847 (anonymous function)load-scripts.php:3 m.event.dispatchload-scripts.php:3 r.handleload-scripts.php:3 m.event.triggerload-scripts.php:8 e.event.triggerload-scripts.php:3 (anonymous function)load-scripts.php:2 m.extend.eachload-scripts.php:2 m.fn.m.eachload-scripts.php:3 m.fn.extend.triggerload-scripts.php:344 (anonymous function)load-scripts.php:2 jload-scripts.php:2 k.fireWithload-scripts.php:4 xload-scripts.php:4 b

Suspect it may have something to do with a conflict with the new distraction free writing editor in 4.1?
