SS4.2
This is a strange one. I am getting an error when entering a date before 1901. It is for a Date field. I noticed it when using the CSV import on the Members table. It is also happening when I edit the field manually.
private static $db = array(
"DateJoined" => "Date",
"DateExpiry" => "Date",
);
