Some of our premium WordPress themes may require Advanced Custom Fields PRO plugin for the gallery manager, reviews and other advanced features.
The plugin is provided with the theme when you purchase it, and the new plugin version is added when a theme update is released. However you have to update this plugin manually.
You should deactivate the plugin and delete it. Then you can install the new version. There are two ways of doing this.
1. You can go to Appearance > Install plugins and select it from the list of recommended plugins.
2. Or you can upload the plugin archive advanced-custom-fields-pro.zip manually from the theme folder /theme_name/vendor/plugins/ via Plugins > Add new > Upload Plugin.
Also you can download free Advanced Custom Fields plugin from the WordPress repository instead. Most of the theme features will work with this plugin version and it can be updated automatically.
