Joomla question

[Michael Sammartano]

I have just successfully installed and configured Joomla for my site, 
and I can login as a user but I get errors when trying to login as an 
Administrator. I get the following error:

*Fatal error*: Call to undefined function: session_name() in 
*/srv/www/htdocs/volinaz/Joomla/administrator/index.php* on line *83

*I do not know php but the error seems to be pointing at  
mosConfig_live_site

I do not know what to do to fix this. Any help would be appreciated.

Mike
