Value Error

[hipnotist 0]

Hi! I have this error in all core's, can anyone help me solve it?

LoadPlayerValue: SELECT id, level FROM player WHERE id >= 0 ORDER BY level DESC LIMIT 50
LoadPlayerValue: SELECT id, gold FROM player WHERE id >= 0 ORDER BY gold DESC LIMIT 50
LoadPlayerValue: SELECT dwPID, lValue FROM quest WHERE szName = 'rankplayer.stone' ORDER BY lValue DESC LIMIT 50
LoadPlayerValue: SELECT dwPID, lValue FROM quest WHERE szName = 'rankplayer.boss' ORDER BY lValue DESC LIMIT 50
LoadPlayerValue: SELECT dwPID, lValue FROM quest WHERE szName = 'rankplayer.monster' ORDER BY lValue DESC LIMIT 50

The last time I changed the system that gives error was 3 months ago.
