Answer 1

Maybe your MySQL has some option such as the NO_ZERO_DATE SQL mode (I think it's not the only mysql config that prevents 0000-00-00 dates). This would prevent you from using 0000-00-00 as a value. It happened to me before that I had a table already created violating that condition. It will not be editable until you change the value or disable what's preventing you to set 0 dates.
