When updated to the last version of SiteOrigin Corp Theme I can’t no longer update pages/post, because it’s breaking the Page Builder plugin. Now Page Builder tab is no longer a tab and appears below WordPress editor, and it’s not usable. Also “Customize” gets broken and you can’t do anything, screens:
It only happens with that theme. I tried about everything, disabling plugins, cleaning caché (WP/Browser), nothing works.
