The free and premium extensions for Groups can be installed by using the appropriate plugin zip file. We recommend the following procedure:
1. Make a full backup of your site including all folders and its database.
3. Download/Purchase the extension you want to install. You will usually obtain access to a zip file which contains the plugin that you are going to install.
4. Go to Plugins > Add New > Upload and click the Choose File or Browse … button and select the zip file of the extension plugin to install.
In this example, our zip file is named groups-restrict-categories-x.y.z.zip. Please note that the filename for your extension plugin will reflect the name of the extension you are about to install and will likely be different.
5. Click the Install Now button.
6. Activate the plugin.
If you have deactivated the Groups plugin that an integration plugin depends upon, you will usually need to reactivate the integration plugin. The integration plugin may cease to operate automatically when the Groups plugin is deactivated.
Unless special instructions are provided along with the integration plugin, you should be able to deactivate the integration plugin and then delete it.
