Most of our themes provide a full version of WPBakery Page Builder.
Any time the plugin is updated, you will find the latest version of the plugin in the config/plugins (or includes/admin/plugins) folder of your theme.
Please note that we need several days to test the compatibility with our themes, and if the new plugin version doesn't include important updates, it may take more time before we update all our themes.
To update the plugin, you can simply deactivate & delete the plugin from your WordPress plugin panel, then reinstall the new version via the "Appearance" > "Install Plugins" panel.
Alternatively, you can reinstall it by uploading the new js_composer.zip file located in the config/plugins folder of your last version of the theme package.
Or, you can replace the wp-content/plugins/js_composer folder on your server via FTP with the content of the js_composer.zip file.
You can switch your website to "Maintenance" mode while doing this.
We cannot sell a license for this plugin inside the theme so we can't give you one.
You need to purchase a license of WPBakery Page Builder ONLY if you need auto-update and support for the plugin author.
