Got more or less the same problem with 2.4.1:
with the pm module I can send messages , I even get the notification that a new message is in the box. However, opening the box tells me I have no private messages.
Uninstalling the pm module, so back to default viewpmsg, I get a blank popup, so no message can be send. However, I do see the private messages already in my box.
Any Ideas?
php 5.x
Edit: ok, found the problem. It appeared pmlite did still do a call to mpmanager.
