I don't see why you're connecting the modernization program with the issue you're having, as the wiki isn't even based on the UCP platform (if I'm assuming right that it's what you referred to). As frustrating as bugs may be, they aren't a rarity nor avoidable on any site either.

Anyway, ListUsers looks to be loading fine for me. If it's still not loading for you, then you may to report the problem.
