By default, the primary domain on the v16 hosting plan will come with the AI sets already installed upon provisioning. However, since the AI set can also be applied to addon domains and subdomains, the client simply needs to choose the sets during the WordPress installation for the domain.
The following are the guided steps:-
1. Log in to your Plesk panel
2. Go to WordPress/WordPress Management
3. A prompt for the WordPress installation will appear, and make sure to select "AI" from the drop-down menu for the Plugin/Theme set.
4. Core WordPress will be installed, with a prompt visible in the bottom right corner, followed by the AI set
5. The subsequent "AI" set will be installed, along with its progress displayed in the bottom right corner
Note: Please allow some time for the plugin and theme set to finish installing.
