Thread:Project:Support desk/Collection Extension: RuntimeError: command failed with returncode 256/reply (2)

I have the same problem. I use trunk version of this extention and MW 19.2. My settings: require_once( "$IP/extensions/Collection/Collection.php" ); $wgCollectionFormats = array(	 'rl' => 'PDF',	  'odf' => 'ODT', );

$wgCollectionArticleNamespaces = array(	 NS_MAIN,	  NS_PROJECT, );

$wgCollectionMWServeURL = ("http://tools.pediapress.com/mw-serve/");

Error message:
