the store as css does not seem to be working on vb4

when i go into admincp it throws me an error about parsing variables?

Fatal error: Only variables can be passed by reference in /home/MYDIR/public_html/includes/adminfunctions_template.php on line 3294

i commented out the code in blue and added the code in red

			delete_css_file($styleid, $csscache["$styleid"]);

			$adblock_is_evil = str_replace('ad', 'be', substr(md5(microtime()), 8, 8));
			$cssfilename = 'clientscript/vbulletin_css/style-' . $adblock_is_evil . '-' . str_pad($styleid, 5, '0', STR_PAD_LEFT) . '.css';

			// if we are going to store CSS as files, run replacement variable substitution on the file to be saved
			if ($vbulletin->options['storecssasfile'])
			{
				$css = process_replacement_vars($css, array('styleid' => $styleid, 'replacements' => serialize($replacements)));
				$css = preg_replace('#(?<=[^a-z0-9-]|^)url\((\'|"|)(.*)\\1\)#iUe', "rewrite_css_file_url('\\2', '\\1')", $css);
				if (write_css_file($cssfilename, $css))
				{
//					$css = "@import url(\"$cssfilename\");";
					$css = "<link rel='stylesheet' type='text/css' href='".$cssfilename." />";
				}
			}

			$fullcsstext = "<style type=\"text/css\" id=\"vbulletin_css\">\r\n" .
				"/**\r\n* vBulletin " . $vbulletin->options['templateversion'] . " CSS\r\n* Style: '$title'; Style ID: $styleid\r\n*/\r\n" .
				"$css\r\n</style>\r\n" .
				"<link rel=\"stylesheet\" type=\"text/css\" href=\"clientscript/vbulletin_important.css?v=" . $vbulletin->options['simpleversion'] . "\" />"
			;
