If you are using ConnectionDB or PlayTime tracker, are they updated to the latest version?

There were updates to the plugins PlayerRankings and ConnectionDB, assuming you updated both, you should be good to go.

my only problem now is with ConnectionDB not working in playtime
I fixed my problem with it by shutting down the server then going to connection db and adding the (approximated) player time in seconds based on the existing players rank at the time the plugins were updated and the data file was wiped (by update)
I have 12 ranks that go from 1,5,15,50,75,125,250,500,750,1000,1500 and 3000 hours, so i just added 20% to that players rank (after they had logged on and connection db had created timestamp) .then restarted the server,  New players time seems to be recorded without any problems (so far)
I will be taking more care when updating plugins in the futured :)
