I have upgraded 3.8.4 to 4.0.1 yesterday. I experienced no problem while doing so. However it seems several problems related to functionality occured. These are:

1- Cant create new PM (white page come)
2- Cant see PM (white page come)
3- when create new post or reply white page come - if refresh i get double post notification but then see it s ok. So posting and replying become 2 step process
4- when editing post after fiinish white page come - no refresh chance like in problem3

Any help is appreciated
