This sounds like that bug which was reported that logs from previous months aren't read (in case there are no logs for this month).
DoUdAr, can you give more details like Menthix asked for?
And/or could you give a description of how you've set all the options related to logging (Plus! settings -> Logs -> Chat Logging).?
