WP-Filebase Pro works with Apache2 and NGINX. Some additional configuration might be required:
- WP-Filebase protects the upload path on the server drive with an .htacess files. Only Apache supports these in-place configuration files, thats not an NGINX thing, because this needs extra I/O. Since NGINX is high performance, there is only a single configuration file. Here you have to disallow the access to your upload path to prevent direct access.
