Thanks for the reports — and thanks Mike for digging into this earlier.
It’s the same problem as the blank CMS admin login. Publish was re-minifying files that were already minified, which mangled the online-editor assets, so the body field never shows up even though the content is still there on the site. I’ve got a fix in place for the next build of Elements which should be out later today
Once you’ve got the new build, republish so the fixed assets are applied.
Thanks @dan - I have my body back! I appreciate all the hard work you and your colleagues are doing. Now I’ve adapted to Elements (from Classic). I’m really loving it.
