Der Fehler taucht auf, weil ein Wert in der Spalte "traff_time" doppelt auftritt. Das darf in der neuesten Version nicht mehr sein https://github.com/i-MSCP/imsc…9fd56f2db1b62b3f257b6a004
Wenn dir egal ist, ob deine Trafficwerte passen, dann lösche manuell doppelt vorkommende Werte in der Datenbank.
Normally, duplicate rows are deleted because we use IGNORE clause but I've just read that a bug exist in MySQL. Even worse, I've just read that the IGNORE clause will be removed in MySQL version 5.7

What is your MySQL version?
Should be fixed. See https://github.com/i-MSCP/imsc…fc430b5e93b5fd9aa5be9d043
i use MySQl Ver 14.14 Distrib 5.5.43, thank you for your fast fix! 
Re ;
No problem. You can update using https://github.com/i-MSCP/imscp/archive/1.2.x.zip
This will be same as 1.2.5 with the included fix.
My Server is up & running, thank you again!
