[Page Builder] – WP 3.6.1 : White screen on editing post

Hello I install the latest version of “Page Builder” on WP 4.5.1 (staging environement) and it works. But on production environment with WP 4.6.1, when I try to add a new post or edit existing, a white screen append :(

Plugin list are the same in both environments, just the WP version is different.

Any helps or update of the plugin is welcome :-)
