hi, once again.
// We need to keep this for backwards compatibility
// Note that this function will only convert dates coming on a string:
// – in english
// – inside the valid PHP date range
// We are only using this when the value being checked is not a timestamp
// And we have tried to avoid that situation from happening
// But for old implementation, this happens for date conditions on conditional fields
public static function strtotime($value, $format = null)
So, I figured out, that date can be saved if the validation is off. Then I call wpcf_fields_date_view($params); in my functions.php from the theme.
If there are any additional questions – feel free to ask.
