Export does not work

I did this in mdocs-downloads.php

function mdocs_download_export_file($file) {
	$filename = $file;
	$file = sys_get_temp_dir()."/".$file;
	if (file_exists($file)) {
			header('Content-Description: File Transfer'. filesize($file));

This gives the correct size of the file … but of course not in the right place. The Content-Length is probably converted automatically to 0 by the webserver when error 500 is encountered.
So I really guess, that this is a webserver restriction, which prevents to pipe the output of readfile to the response …

sounds like it, maybe you could ask your service provider for some insight into this puzzle. They maybe able to give you a solution or tell you what I could do to make it work.

I have the same problem. Is there an alternate method of exporting my files without downloading them one at a time?

no export is the only way currently.

Ok, but export does not work. Any idea when this feature will be fixed?

in the case of the user above the problem was not a issue with mDocs, it was a server configuration. I don’t know how your server is configured but I would start there. Look at your server logs configuration files and error messages to find out why this 500 error is occurring.
