- The theme includes a license for this plugin so you don’t have to buy it.
- You don’t have to activate the plugin license, it’s already activated.
- You can’t update Visual Composer directly from it’s producer.
- You don’t have to worry about the plugin update warnings.
- We provide updates on a regular basis, after we test the plugin for theme compatibility we include it in the latest theme update, inside the ../plugins folder
