My issue is that I’m getting the following error “The backup of this post in your browser is different from the version below” on page and post edit screen. the only customization I added to the theme is the jet pack infinite scroll type, container and post_per_page.
This is a fresh install of wordpress 4.4.2, on witch i installed shapely + content, latest jetpack plugin 3.9.6 , latest yoast plugin 3.1.2, and imports plugins.
I did a little digging, and found that in extras.php in function shapely_admin_style()
the style of the notice wrapper is set to “display: block” regardless to the fact that it can be hidden so it displays it anyway.
