Nginx give access to subdirectory

We’re running a WordPress site on a Nginx server, I am now trying to install Piwik there in the /stats folder.

This is the default Nginx configuration that came with the install, I added the “/stats” block myself, but it doesn’t work – it gets rendered by WordPress whenever I go to mysite.com/stats instead of going to that folder.

Desired behavior would be that the /stats subdirectory (and all files and directories in it) is just parsed by PHP as would be on a default install without Nginx rules

Any clue what I’m missing?
