vBulletin Problem - implode()

[AncientSage]

[code]Warning: implode() [function.implode]: Bad arguments. in /admincp/index.php on line 128[/code]

There is my error. The line is as follows:

[code]$vbulletin->GPC['navprefs'] = implode(',', $vbulletin->GPC['navprefs']);[/code]

The implode function should be working, given that it is an official vBulletin release. However, there seems to be something wrong with it (PHP version IS above required by vBulletin).

[code] $groups = explode(',', $vbulletin->GPC['groups']);

foreach ($groups AS $group)
{
if (empty($group))
{
continue;
}

$vbulletin->input->clean_gpc('r', "num$group", TYPE_UINT);

for ($i = 0; $i < $vbulletin->GPC["num$group"]; $i++)
{
$vbulletin->GPC['navprefs'][] = $group . "_$i";
}
}

$vbulletin->GPC['navprefs'] = implode(',', $vbulletin->GPC['navprefs']);[/code]

Help appreciated.

could be something simple.. try changing that line to these 2 lines (the way I'd do it)

$navprefs = $vbulletin->GPC['navprefs'];
$vbulletin->GPC['navprefs'] = implode(',', $navprefs);

I'm thinking the problem is where the two single quotes are around 'navprefs' in the class, it's assuming thats where to start or something.
