We have to notice that we take care of all the bundled plugins in our theme. So, in every new release of the Theme the latest compatible version of Visual Composer is included. This also applies for all bundled plugins: e.g Visual Composer, Revolution Slider etc. It is needed to test any update of these plugins to ensure the compatibility with our theme before we include these in our theme. Especially for the Visual Composer as we do not just provide a copy of it but an extended page builder with our own grid system and handcrafted elements.
You don’t need to purchase an additional license of Visual Composer for our Themes and there is no reason to worry for warning messages about the plugin license activation.
To make sure you have the latest version of the bundled plugins you just need to update the Theme. This way you can update them from the integrated TGM Plugin activation dialog.
The included Visual Composer version can be found also in the release notes of the Theme.
So make sure that you have the latest Theme installed and updated all the bundled plugins before you open a ticket.
