This is the block of code I've been working on for hours ... :(

--------------- nginx.conf ------------
server {
listen 80;
server_name sitea.com;
rewrite ^(/hiddendevpath)(.*)$ http://sitea.com/ ;
rewrite ^(.*) https://sitea.com
}

------------- testing below ----------

sudo /usr/sbin/nginx -t
Error: nginx: [emerg] invalid number of arguments in "rewrite" directive in /etc/nginx/nginx.conf:44
