@Crazy5650. Yes. I am glad the default is NULL. It is supposed to be NULL by default. The error you experienced occurs because of the invalid value “0000-00-00 00:00:00” being inputted into the field. I dealt with this issue since version 3.6, when MySQL deprecated the use of that value. I am not too sure how those values got into your table. There shouldn’t be anything in the code that does that.
Did you recently upgraded your MySQL from an older version to a newer one? Or maybe updated the extension from an older version?
