For the last four days, I've been having intermittent problems uploading photos to my albums on Facebook, using FriendCaster Pro. FriendCaster Pro will show a successfuly upload, but the photo never appears in the album. Photos will upload to some albums, but not to others. I also tried uploading with MB Notifications and it gave me an error containing the word "null". I have checked to be certain that the albums are not full. FC Pro and MB both have full permissions.
