Since OnDemand 5.2 has launched, members of my team and I cannot create Events associated to a user. When we start typing into the Who field, it says "no users found". If you type the whole username of a user you know exists (for example, myself), it says "enter a valid user".
Please advise on what could be causing this.
One other change I've made was renaming a space, but I don't think that could have done it...
