Strange Download Issue

[kp-emagine]

Downloaded the zip, unziped, updated compser using php connector
All files show, great :)

I can also double click on pdf's, and images, and they all preview fine

However, when I try to download a file, I get an error message
could not be saved, because the source file could not be read.

I went through all the FireFox diagnosis, same issue, and it doesnt do it for your demo site....

If it helps, here is my connector.php

<?php

error_reporting(E_ALL); // Set E_ALL for debuging

// // load composer autoload before load elFinder autoload If you need composer
// // You need to run the composer command in the php directory.
is_readable('/myfullpath/vendor/autoload.php') && require '/myfullpath/vendor/autoload.php';

// // elFinder autoload
require '/myfullpath/php/autoload.php';
// ===============================================

	return $basename[0] === '.'                  // if file/folder begins with '.' (dot)
			 && strlen($relpath) !== 1           // but with out volume root
		? !($attr == 'read' || $attr == 'write') // set read+write to false, other (locked+hidden) set to true
