Hi I'm currently trying to Update LimeSurvey to Version 3.27.20
I have to do a Database Upgrade from current Database Version 180 -> 365(mysql)
As soon as i start the Update it tells me:CDbCommand couldn't execute the SQL-Statement: SQLSTATE[22007]: Invalid datetime format: 1292 Incorrect datetime value: '0000-00-00 00:00:00' for column 'submitdate' at row 98So right now i've tried to install a Backup Version of LimeSurvey to use the Check Data Integrity but nothing happens as I start it.
