nginx boa

Hello,

I just received an email from a client that their site is down. I see that all sites are down, as I believe Nginx is no longer running. When I try to restart it I get the message:

nginx: [emerg] unknown directive "PATH=/usr/local/sbin:/usr/local/bin:/opt/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" in /data/disk/o1/config/server_master/nginx/vhost.d/BOA.sh.txt:50
