Social groups error: Only variables can be passed

[VGPelega]

Hi there, I have come back to my vb social groups mod, and I am at a stage where I could really do with using it on my website.

Let me give some background information. I upgraded from 3.6.7 - 3.6.8 then I went onto vb, 3.7 gold, and now I am running 3.7.2. But I have never been able to use the social groups feature, and each time I try to create a new social group, I get the following error:

Fatal error: Only variables can be passed by reference in /home/MYROOT/public_html/forums/group.php on line 804

This is the line of code on the groups.php file (plus the surrounding code lines 799 - 813):

// ############# Do we need group owner info? ############################
if ($_REQUEST['do'] == 'edit' OR $_POST['do'] == 'doedit' OR $_REQUEST['do'] == 'create' OR $_POST['do'] == 'docreate')
{
if (!empty($group))
{
$groupowner = fetch_userinfo($group['creatoruserid']);
cache_permissions($groupowner);
}
else
{
$groupowner = $vbulletin->userinfo;
}
}

// ################################################## #####################

The line in red is line 804, and I am just really confused as to what is the cause of this fatal error. Could someone point me in the right direction in order to repair this issue?

I am really at a loss on this, and don't know where to start, but I am very willing to make a start. Any help would be appreciated.

disable all your hacks
upgrade to the latest version of vB
bring the complete error you see on screen, not the line related to it.

OK, firstly, I can not upgrade my forum software to the latest version right this second.

As for disabling ALL of my hacks, how would I go about getting them all re-installed again (or working again) As this seems to be the bog standard response to an issue with vb.

And the last thing you said doesn't make much sense to me,

bring the complete error you see on screen, not the line related to it.

I posted the complete error that the page gives me, but this only appears when I click on "Create a new group" on the groups page.

Sorry for being impatient, its just I have never had a response to this question that seems to help me. I am just worried about losing my hacks, just for the sake of having social groups loading.

I systematically disabled all of my hacks, as you requested, and it was resolved when I disabled the "members who have visited" hack.

I should be able to figure the rest out myself. Thanks for your help.
