The theme needs nulling to install ‘pro’ demo content (and to remove nag messages). The nulling takes place in the auxin-elements plugin, not the theme. Install the theme first. Then go via cPanel and open the file within your plugins folder below; In the file, auxin-elements/includes/general-functions.php find the function auxin_is_activated which starts around line 2024. Add this to the start of the function code: return true; Save and close. You can now install all the demo content and the nag messages are gone.
