In vb4.2.5 PHP 7 I get this error when I try send pm.

Call to undefined function split() on line 3 in /var/www/vhosts/TEST FORUM/httpdocs/private.php(1461) : eval()'d code
#0 /var/www/vhosts/TEST FORUM/httpdocs/private.php(1461): eval()
#1 {main}

When mod is disabled all is fine.
This mod has 2 plugins, when disable this, pm works.

private_newpm_start

if($vbulletin->options['advanced_pm_manage_onoff'])
{
$madkour_banusers=split(',', $vbulletin->options['advanced_pm_manage_BannedMembers']);
$madkour_bangroups=split(',', $vbulletin->options['advanced_pm_manage_BannedGroups']);
if ($vbulletin->userinfo['posts'] < $vbulletin->options['advanced_pm_manage_reqPosts'])
{
standard_error($vbulletin->options['advanced_pm_manage_reqMessage']);
}
if (is_member_of($vbulletin->userinfo, $madkour_bangroups))
{
standard_error($vbulletin->options['advanced_pm_manage_BannedGroupsMessage']);
}
if (in_array($vbulletin->userinfo['userid'], $madkour_banusers))
{
standard_error($vbulletin->options['advanced_pm_manage_BannedMembersMessage']);
}
}
/*
standard_error($vbulletin->options['advanced_pm_manage_BannedMembersMessage']);
*/

Any idea ?

Thanks
