My theme (uncode by undsgn) uses a customised version of Visual Composer (VC) page builder.
The default setting is to allow VC for pages only, but in the “Role Manager” it is possible to manage which roles can use different VC elements. For example, you can enable the different roles to use VC with posts also.
This works for the Administrator, but for all other roles, even if they are explicitly customised in the “Role manager”, it is impossible to enable use of VC with posts.
I’m not sure if this is connected with URE, but I have a test version of my site which doesn’t use URE, and doesn’t have this problem. It is possible to enable other roles to use VC in posts.
My question is : are you aware of a possible problem here, and can it be fixed?
