As you can check at my private details, the homepage layout has some issue related with the CSS (missing backgrounds and styles), despite at the Cornerstone view it looks as expected. It only happens on the homepage, the rest seem to be ok.
I answer myself. It was because the styles cache within X Settings. I found that previous post from some hours ago
Maybe you should update the way the cache works. It’s not reasonable that without making any changes the cache affects the layout.
But anyway, it doesn’t work as expected as is says:
Clear Style Cache
For slower page loads Elements will remember the CSS generated when they were last saved. This is automatically cleared when Cornerstone is updated. It may be useful to clear manually if any Elements are missing styling.
