4.1.8 - registration - COPPA problem error

[ka81]

Hello.
please, help me how to fix error with registration:



when in /admincp/options.php?do=options&dogroup=register in COPPA Registration System set to Enable COPPA , then new people can register on board, but they heve to take pre-step in registration - choose date of birth.

if it is set to Disable COPPA, then there is no pre-step, but when somebody registering it says (after Click to Register) error:

You have left a required field blank.

how to fix error, please??
