TOPIC: Strange error message???

As you can see on the attachment I get this strange warning. I'm not a PHP expert (by far) so it may be quite elementary...??

This is the warning:
Warning: Invalid argument supplied for each () in (../the path in my system/) sysswfcontent.php on line 104

Line 104 says:

foreach ($tmp as $key => $content){
$content = $swfobject->renderSWFTag($content);
}
if ($content==false)return;
$_document->_buffer[$key] =& $content;
}


PLEASE HELP

That error message is related to a different plugin. Haven't seen that before. Not sure which plugin that is, but whatever it is, it is trying to load unsuccessfully on that page for some reason.
