Hi!

There's an error in your code:

<?xml version="1.0" encoding="ISO-8859-1"?>

<plugins>
	<plugin active="1" product="vbulletin">
		<title>Force Styles for Selected Usergroups</title>
		<hookname>style_fetch</hookname>
		<phpcode><![CDATA[if (in_array($vbulletin->userinfo['usergroupid'], array(a,b,c)) || (in_array($vbulletin->userinfo['membergroupids'], array(d,e,f)))
{ 
$styleid = 8; 
}]]></phpcode>
	</plugin>
</plugins>

You forgot a closing ")" in the if-statement (before "{") ...

Regards,
Christian
