404 using memcached on Nginx

Hello, after adding this code from your plugin at my nginx config
## GZIP
gzip_static on;

## CHARSET
charset utf-8;

## INDEX LOCATION
location / {
error_page 404 405 = @nocache;

if ( $query_string ) {
return 405;
}
if ( $request_method = POST ) {
return 405;
}
if ( $request_uri ~ “/wp-” ) {
return 405;
}
if ( $http_cookie ~ (wp-postpass|wordpress_logged_in|comment_author)_ ) {
return 405;
}

default_type text/html;
add_header X-Powered-By Cachify;
set $memcached_key $host$uri;
memcached_pass localhost:11211;
}

## NOCACHE LOCATION
location @nocache {
try_files $uri $uri/ /index.php?$args;
}

Im getting 404 errors in all of my site, just home is loaded, if i go to any other section / page i get 404 error.
