I’m trying to optimize our database because we have a lot of users and the wp_usermeta table is getting really really large. I notice that every single new users gets a row added with the key wp_user_level but when I do a multi-file search of my entire site, that key isn’t referenced a single time. So I’m stumped. What the is it? And can I get rid of it without anything catching on fire?
What is the purpose of wp_usermeta key: wp_user_level
