Message:  Trying to get property of non-object
File:  /home/xyxyxyxy/public_html/xyzxyz.org/ow_plugins/ynsocialbridge/controllers/socialbridge.php
Line:  49

I go to line 49 and it reads:

"            if ($clientConfig -> apiParams)"


and here is the php code prior and after from line 40 to 63:

//get callback URL
        $callbackUrl = OW::getRouter() -> urlForRoute('ynsocialbridge-connects');
        $core = new YNSOCIALBRIDGE_CLASS_Core();

        $arrObjServices = array();
        foreach (array('facebook', 'twitter', 'linkedin') as $serviceName)
        {
            //check enable API
            $clientConfig = YNSOCIALBRIDGE_BOL_ApisettingService::getInstance() -> getConfig($serviceName);
            if ($clientConfig -> apiParams)
            {
                $params = unserialize($clientConfig -> apiParams);
                if(!$params['key'] || !$params['secret'])
                    continue;
                $obj = $core -> getInstance($serviceName);
                $values = array(
                    'service' => $serviceName,
                    'userId' => OW::getUser() -> getId()
                );
                $tokenDto = $obj -> getToken($values);
                $profile = null;
                $connect_url = "";
                $disconnect_url = OW::getRouter() -> urlForRoute('ynsocialbridge-disconnect') . "?service=" . $serviceName;
                if ($tokenDto)


So my question is:

What do I need to change? (edit)
