Shipping broken. Won't read templates

[cyberalt1]

<?php 
require __DIR__ . "./../vendor/autoload.php";

#echo "Hello world!";
#echo __DIR__ . "/templates/";

$latte = new Latte\Engine;
$latte->setTempDirectory(__DIR__ . "/templates/");
$params = [];
$latte->render("index.latte", $params);

?>

This refuses to run index.latte, the template folder 10000000% exists and it just says not found

It seems you confused temp directory and templates directory.
