Problems after going from PHP4 to PHP5

[subnet_rx]

Yeah, I followed the advice. There are no plugins using that hook. Like I said, I've edited all that the search finds that uses array_merge. It finds an error on 1259, but there is no hook on that line, so that tells me that there is code being included server side giving that file more lines. I need to see it as the server sees it.

EDIT: Nevermind, I was looking for userinfo, not fetch_userinfo. Here's the code causing the problem. It's from the welcome headers addon.

if (THIS_SCRIPT == "index")
{
	global $globaltemplates;

	$globaltemplates = array_merge((array)$globaltemplates, array('forumhome_welcomepanel_' . $vbulletin->options['wp_style']));
}
