How to configure the nginx and php-fpm bundle to be compatible with the Opencart Custom Product Designer 3.0.0 module?

Question

PHP

The problem is that when following a link like ".../tshirtecommerce/admin/index.php/user/login" we get 404 errors. A link like ".../tshirtecommerce/admin/index.php" works fine. When examining the nginx logs, it turned out that nginx cannot find the ".../tshirtecommerce/admin/index.php/user/login" folder, which is what it writes about. The internal logic of the script is unknown, since there is no ".../tshirtecommerce/admin/user/login" folder in the system either, but this does not prevent this module from working perfectly in a local Denver that works on Apache.
I hope they help me here, thanks! !!
