Hi There,
When I first view your site, this is what I see:
And as soon as I log-in, the site gives me the correct layout.
Not only that, like Rubin said above. I also saw an error coming from Autooptimize, even though like you said above you already deleted it. So that means that your site is still giving us resources that does not even exist anymore.
Most of the time, that issue is related to CACHING, so I did go ahead and Purge your SG Cache. But that did not resolve the issue. I did continue to look around on your plugins and I saw another caching plugin (W3 Total Cache) being deactivated. Deactivating a caching plugin does not mean it will clear its generated cache, so I did activate it and Purge its entire cache as well. And that resolves the issue about the layout. Please clear your browser’s cache if you still see the issue on your end.
But it did not end there, right? because we still have the V2 element not showing issue.
We release the V2 element on X 5.2.0 update, but you still have the X version 5.1.1, that means your X and Cornerstone is not compatible. Please update both to the latest version (X 5.2.3 / CS 2.1.4)
Updating Your Themes and Plugins
Remember to clear all caches (plugins, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope this helps,
Cheers!
