About User Roles in WPbakery (Solving) (CRITICAL ISSUE)

WPBakery version 5.6 in this template but this plugin has a critical issue. This issue is, user roles. Nothing changes when you set user roles. All registered users can change / edit your pages or posts as their wish or create new ones. This is not skywarriorthemes’s issue. This is only about plugin. I will share solution. Following steps:

1- Disable WPBakery Plugin
2- Delete WPBakery Plugin
3- Install my shared WPBakery plugin and active
4- Install second plugin (User Role Editor) and active
5- Open the User Role Edtor plugin and set up roles as you wish

Problem solved.
