			else
				error.insertAfter(element);
		}
	});

	{$validator_extra}
});
</script>

I hope you can help me!

Solved it. And that is why you probably did not respond. It is a custom theme, Emerald that I customized.

What was wrong is that the script was not called in the template member_register.

<script type="text/javascript" src="{$mybb->asset_url}/jscripts/validate/jquery.validate.min.js?ver=1821"></script>

I placed this directly under the headerinclude and all was fine.
Like this.

<html>
<head>
<title>{$mybb->settings['bbname']} - {$lang->registration}</title>
{$headerinclude}
<script type="text/javascript" src="{$mybb->asset_url}/jscripts/validate/jquery.validate.min.js?ver=1821"></script>
