Good morning, I created a personal file, which is not in the file hierarchy of WordPress, this file is called reserva.php. In this file, do an include wp-load.php functions to use WordPress. The problem is that access to that file is by http://www.miweb.com/wp-content/themes/mitheme/cart/reserva.php and I would like to go through http://www.miweb.com/cart/reserva.
