Hi, I found a likely bug in the RC2 release:
Fatal error : Cannot declare class Cornerstone_Header, because the name is already in use in /tesztoldalak/genedia.ethermedia.hu/wp-content/themes/pro/cornerstone/includes/classes/regions/class-header.php on line 3
I updated on my local dev environment. Everything worked fine -> exported the site with WP-MIGRATE (worked with previous versions) and uploaded it to http://genedia.ethermedia.hu/
Upon finishing the upload, this error came up.
