Thanks for your response.
However, I am a newbie to both WordPress and LifterLMs so I do not know how I could have set up a custom admin panel. Come to think of it, doesn’t LifterLMS create a restricted admin dashboard for instructors? Is that a custom dashboard?
Anyway, as I was able to create instructors in the 30-day LifterLMS trial platform and on a local WordPress installation, I began to suspect something was wrong with my WordPress installation. I re-installed WordPress, made sure the PHP version was 7.2, and voila! … I was able to create instructors.
