I am using first time Acymailing 6. In Acymailing 5 there was a plugin for birthdays. I tried to use the date field instead of plugin ..without %y in subscription forms (as we don't need the year and not everyone would be willing to provide year). When I set date with year included in the field, form can be filled no problem, without %y no way it form can be submitted. System display errror ( set by me of course ) same way like entry wasn't done. Can anyone help to tell me what I am doing wrong?
