I have made it in my 3.6.0 this way. I haven?t tested myself, but think in 3.6.1 and 3.6.2 it should also work...
AdminCP --> vBulletin Options --> User Registration Options --> "Deny registration for users aged under 13 years" --> Save
After that edit the
register.php this way:
Find:
PHP Code:
if (mktime(0, 0, 0, $vbulletin->GPC['month'], $vbulletin->GPC['day'], $vbulletin->GPC['year']) <= mktime(0, 0, 0, $current['month'], $current['day'], $current['year'] - 13))
Replace with:
PHP Code:
if (mktime(0, 0, 0, $vbulletin->GPC['month'], $vbulletin->GPC['day'], $vbulletin->GPC['year']) <= mktime(0, 0, 0, $current['month'], $current['day'], $current['year'] - 18))
After that you can edit the error message for the users in the phrase:
$vbphrase[under_thirteen_registration_denied]
