[META] user search is not working

In the user tab, user search is not working (returns no results).

This was reported in June :

in the user tab, user search is not working (returns no results)

along with :

in the moderation que, ‘Send Message’ button does not work, simply returns view to the top of the mod que.

What is going on? Is this being looked into at all?

User search works for me.
