Nginx PHP file plaintext rendered - nginx

Question

I'm having a main domain example.com and an example.com/admin/. This admin domain has a different document root and will render the admin interface. The problem currently is that the file is server plain-text by nginx. So I can basically see the index.php file. I'm trying to figure it out, but no success yet.
This is my nginx config:
server {
listen 127.0.0.1:8080;
server_name www.example.me;
rewrite ^(.*) http://example.me$1 permanent;
}
server {
listen 127.0.0.1:8080;
server_name example.me;
root /var/www/example.me/laravel/example/public/;
index index.html index.htm index.php;
error_log /var/log/nginx/example.me.error.log error;
access_log /var/log/nginx/example.me.access.log;
port_in_redirect off;
merge_slashes on;
client_max_body_size 20M;
error_page 404 =301 http://example.me;
location / {
#Don't use slash at end
rewrite ^/(.*)/$ /$1 permanent;
# add rewrite rule here:
# block access to /index.(php|htm|html)
if ($request_uri ~ "/index.(php|html?)") {
rewrite ^ /$1 permanent;
}
if (!-e $request_filename) {
rewrite ^.*$ /index.php last;
}
}
location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
location ^~ /admin {
root /var/www/example.me/zend/public/;
index index.php;
try_files /index.php$is_args$args $uri;
auth_basic "example Admin";
auth_basic_user_file /var/www/example.me/zend/public/.htpasswd;
rewrite_log on;
access_log /var/log/nginx/adminexample.access.log;
error_log /var/log/nginx/adminexample.error.log notice;
location ~ \.php$ {
include fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
#fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
#fastcgi_param SCRIPT_FILENAME /var/www/example.me/zend/public$fastcgi_script_name;
}
}
}
