Hi -
Looks like this is still an issue:

Visual Composer is pretty much the standard enhanced editing plugin, and comes bundles in many, many themes. It has its own Role Manager section, but doesn't allow for the granular control + custom roles that URE does. Would be great if the two could play nicely together?
