Just updated this as well as connectiondb and it has reset the players hours which has annoyed the one with 3750 hours since the plugin was installed, The actual rank is still there but not the hours,

It might be a good idea to warn people that as this update mentions a ConnectDB update that if they use that update it will wipe their ConnectDB data file and really piss off their players.                                  

PlayerRankings has nothing to do with ConnectionDB or PlaytimeTracker in terms of tracking and maintaining player time. You'd have to take this up with the developers of those plugins and my update notes included "for ConnectionDB update".

Edit: You should still be able to use an older version of ConnectionDB and PlayerRankings to restore hours as long as you still have a backup of ConnectionDB data to restore player hours.

ConnectionDB was updated over two months ago and worked perfectly with this plugin till you updated it, Then all data was lost and there does not seem to be a connection between this plugin and connectionDB as it does not show any increased time even though connectiondb and this plugin have been reinstalled several times the time played stays the same, which is 0
I dont  know which plugin is not working i only know that the players on my server are complaining to me, and that any rewards for ranks (hours) will not be available to them for a very long time.

I see now, I will check my plugin and test it.

Updated. Please let me know if you receive a "There is no plugin tracking the playtime for players" warning, otherwise it should be working fine.

im also here the data has wiped and connectiondb does not update the playtime higher than 1s

mine is now working although i have to wait for the players to come back on and take a note of their rank and wait until server is empty then shut it down and add the time played (plus 20% ) in seconds for each player in ConnectionDB data file, Then restart the server ,
The new players times work normally so i dont have to do anything to them.
