After compiling a test module that sets a variable equal to "test
successful", I get a "directive is duplicate in (path to conf file)"

Can someone explain what's going on? I tried googling the error, but found
nothing useful.
This is my conf file :
worker_process 1;
events {
worker_connections 1024;
}
http {
include mine.types;
default_type application/octet-stream;
log_format main ‘$remote_addr’;
testAPI 7;
access_log logs/access.log main;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
