Error: PHP message: PHP Notice: Undefined index: user_status

I followed the set-up instructions and could access the page permission and after giving permission to the server logs the following error:

*68 FastCGI sent in stderr: "PHP message: PHP Notice:  Undefined index: user_status in /var/www/netvizz/index.php on line 114" while reading response header from upstream, client: 188.114.99.247, server: demetra.labic.net/netvizz, request: "GET /netvizz/facebook.css HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "mysite.com", referrer: "https://mysite.com/netvizz/?code=AQC-RWKHuMp3mOTWENe3YLTICzUrauWK52gcgCOwyGGrkh9yv4ExDttoWu06xlCNdYpWZeKfpIlG7ZZAuHU2BBnP-5ddb26ubDTZ6ZBE87AcMB9D-BigzTexBvEpOef4AXpzsU-X2dY5KU10DY_kn2nXRZtsJOmQiKKDZIOEDYdHR_0daeCXvGOb99l10DgnUJ09XMsyu9vafBRCA90DAlUi1clh-vcwoG6_e_F6X-UpJxH-m2T2-2q4yMfUcPQSyzKO9fI-4qTYrdez14dpnqb_g8Rkbc-41EocwfyLBNErfVEj7xMLwH5GTn0iHunlKALI0LNe1xHfaJHk3oaxW8qp&state=62e128934f9e3b7bcb04a02486c893ac"
