Thank you for you help, but those I have tried.
I tried it in chrome, IE and opera, a i have already checked, if the config.php is in ANSI.
But i don't know how to check, if there isn't any problem with sessions, when I'm just a guy working on a school project, on school servers.
Would be helpful for you, if I'd message you the phpinfo?

Really thanks for help.

Also check if the folder defined at the "session.save_path" setting exists and is writable.

I really appreciate your help. I just sent you pdf with the php info.
I also don't know, where to find this session.save_path. In which file it is?
Thank you very much ..

I don't see any PDf file here, please post it here.

As for the save_path setting: That can be found at the php.ini configuration file of your webserver.
Tell your provider to check and fix this if necessary. Your problem description indicates that this might cause the trouble.

Here is my php info ... Im going to write to the admin of our servers.
here: survey.natur.cuni.cz/phpinfo.php

here it is. it was too big to be uploaded, very sorry.
survey.natur.cuni.cz/phpinfo.php

Only possible cause of the problem I can think of is the session.save_path setting which your provider should be able to fix.

Hi, again, thank you very much for your help.
Still, the problem presists. My IT-men told me, that he has checked the session.save_path, and its ok, that he has checked the html headers, if there was any cookie received. He told me, this:
Set-Cookie: PHPSESSID=some-weird-numbers-and-letters; path=/; domain=web.natur.cuni.cz

"web.natur.cuni.cz" is real hostname of the server,on which our virtual server is running, but as I understood it, we should tell to LS to be demanding this address: "survey.natur.cuni.cz".

I hope it does make sense. Could you tell me, if there is any possibility to solve it?
Thank you ...

Just for others, who are experiencing similar problem, here is how I had to solve it.
I had a homepage with a link to the limesurvey admin. As you allready know, this my space in server is using aliases, and therefor the link leading to the admin page was also with this alias. That was the problem, because the session was intended to be set up for the true URL, not with the shortened one. So I just had to make this link with the true link to the admin page.

Hope this can help you. L
