Rechecked it on a local system (moewes portable):

• limesurvey 1.91+ build 10089
• php 5.2.8
• MySQL5 (5.1.30)
• Apache2 (2.2.11)

same result, error warning:

"FEHLER
Es tut uns leid, aber Ihre Sitzung ist abgelaufen.
Entweder sind Sie zu lange inaktiv gewesen, Sie haben Cookies deaktiviert oder es gab ein Problem mit Ihrer Verbindung.
Bitte kontaktieren Sie Your Name ( your@email.org ) für weitere Unterstützung."

register_globals on or off does not affect the problem
session.save_path is set to a valid path

No problem here, can't reproduce.
Unless we get direct access to such a system to debug it there is not much we can do.

Dumb question: Have you tried clearing your cache and cookies?

I've faced the same issue on both versions 1.90 and 1.91 (even latest one, 1.91 plus). Here's how I solved (I've uploaded the file index.php including what I describe below).

In the file index.php, locate the following block:

if (!isset($_SESSION['s_lang']) && (isset($move)) )
// geez ... a session time out! RUN!
{

-- WHAT I DISCOVERED --
Right there it is checked that the s_lang parameter is set (and thereis some command in the variable $move, if you are to answer some survey, it should be "movenext"). Well, s_lang is correctly set before somewhere else, but for some weird reason it is lost just right before that point in the code (you can monitor $_SESSION array if you want to check this).

-- HOW I SOLVED IT --
I just added the following few lines

if (empty($_SESSION))
@session_start();

-- RESULT --

Here's how your index.php file should look like after including the fix (I include a few lines of context)

if (isset($_SESSION['srid']))
{
$saved_id = $_SESSION['srid'];
}

if (empty($_SESSION))
@session_start();

if (!isset($_SESSION['s_lang']) && (isset($move)) )
// geez ... a session time out! RUN!
{

jquinter, thank you for your patch but the thing is that your patch deals with a differnt issue than reported here (both 1.90+ and 1.91+ not working).

THe issue above is reported to be: Works on 1.90+ and does not work on 1.91+. I yet have to see such an installation.

Can anybody provide access to such a system? Of course all information will be kept confidential.

Hi,

please look at http://www.limesurvey.org/de/forum/deutsches-forum/61028-problem-nach-update-auf-191#61091

There you will find link to a portable system with a test-survey to check out.

I downloaded the ZIP file, but on running the apache it crashed. I downloaded a clean MOWES installation from the vendors page, installed it and copied over the Limesurvey dir and the limesurvey database from the provided ZIP file. It works like a charm here so it is still not reproducable and must be some issue with your system.

I guess the direct access to such a system would be more viable.

ok, so I'll install a separate 1.91 on my account, but this will take a while

btw. would you please be so kind to upload your working copy of mowes+lime?

Well, it works here so I am not in a hurry :p

Just uploading it - will be availabe under httP://www.limesurvey.org/mowes_portable_lime.zip

thx :-)) I'll test it.

Open index.php, go to line 81 and replace the line

if (!isset($_SESSION))

with

if (!isset($_SESSION) || empty($_SESSION))

This problem affect all installations which have 'register_globals' activated in the PHP configuration (which you should rather not have activated in general for security purposes - any software relying on register_globals to be activated should be shot dead and buried)

Thanks to Gunnar Grieger for access to an affected system. Fixed in rev. 10113

Released new 1.91+ version.
