传递的参数无效 - 正在工作，现在不是

Question

我已经让这段代码工作了几年，现在我不相信有任何改变，但几天前它刚停止工作并开始给我这个错误：

  

警告：implode（）[function.implode]：传入的参数无效   /home/vss/public_html/dashboard/modules/addons/vssapp/classes/class.adminarea.php   在第277行

     

捕获致命错误：无法转换类stdClass的对象   串入   /home/vss/public_html/dashboard/modules/addons/vssapp/dropbox/Dropbox/OAuth/Consumer/Curl.php   在第102行

class.adminarea.php ：

       foreach($imagedata as $image){
            $data = '';
            $sizes = getimagesize($image['path'].'?dl=false');
            $data .= 'Filename: '."".$image['filename']."\n";
            $data .= 'Image Size:' ."".$sizes[0].'px x '.$sizes[1].'px'."\n";
            $data .= 'Path: '."".$image['path'].'?dl=false'."\n";
            $data .= 'Rooms: '." ".ucwords(implode(", ", array_keys(unserialize($image['rooms']))))."\n";
            if($image['couch'] != ''){$data .= 'Couch Position: '."".$image['couch']."\n";}
            if($image['headboard'] != ''){$data .= 'Headboard Position: '."".$image['headboard']."\n";}
            if($image['generaldiningroom'] != ''){$data .= 'Dining Room Position: '."".$image['generaldiningroom']."\n";}
            if($image['generallivingroom'] != ''){$data .= 'Living Room Position: '."".$image['generallivingroom']."\n";}
            $data .= 'Furniture: '."".implode(", ", unserialize($image['furniture']))."\n";
            $data .= 'Info: '."".$image['info']."\n\n--------------------------\n\n";
            $imagedetails[] = $data;
        }

Curl.php ：

        // Check if an error occurred and throw an Exception
    if (!empty($response['body']->error)) {
        $message = $response['body']->error . ' (Status Code: ' . $response['code'] . ')';
        throw new \Dropbox\Exception($message);
    }

    return $response;
}

对发生的事情以及如何解决问题的想法？
