Download selected emails issues an empty zip file

[Former user]

Hi I'm using the vmware image provided on your download page, and everything is working fine it seems, except the download selected emails link. It presents a blank zip file (literally, 0 bytes in size).

I performed an apt-get upgrade (and it updated mysql client and server is all I think), but the issue remains.

I can see libzip1 is installed as well.

please edit /var/www/piler.aaa.fu/model/message/restore.php and replace the ~12th line ($filename = DIR_TMP ....) with the following line:

$filename = DIR_BASE . "tmp/" . $randomid;

or if you want to spare your fingers :-), then download the master branch, and replace model/message/restore.php

I have the same issue with the latest version. The restore.php has already the correct line and libzip2 is installed.

Solved. There was a permission problem in "/var/www/piler/tmp".
