I’ve not gotten this to work, my fix didn’t actually fix the code, only made the wp-admin area not break.
I’d be an unhappy camper if I’d purchased this thing. Developer seems MIA.
So I changed the _fill_user to get_user_meta and now wordpress doesn’t completely crash, however passwords are not expiring.
Considering this software has some sort of activation to a “homeip.net” I’m not sure I could ever rely on this thing.
