  • Hi,

    Sorry for the inconvenience.

    It seems you have very limited role access to the site. Please make sure and upgrade your role so you can manage the plugin’s settings.

    I was Super Admin. Administrator on that site. Maybe multisite issue.

    Hi

    It’s a multisite installation?
