Help Please!? - Sudden fatal error on sugarcrm

[amcrann]

Just five minutes ago I was using sugar 5.1 and everything was fine. I performed a search and received this message:
Fatal error: Call to undefined function can_start_session() in /chroot/home/twozeroo/2010brochures.com/html/sugar2008/include/MVC/SugarApplication.php on line 382

Does anyone have any ideas how to fix this? All I did today was a backup of the db and the site files, but that was hours ago and I've been using the program just fine until now.

I think there is coding error in includes/utils.php:

function can_start_session(){
$session_id = session_id();
return empty($session_id) ? true : false;
}

This makes sugarcrm think it cannot start sessions when it can. I think the code for the above function needs to read:

function can_start_session(){
$session_id = session_id();
return empty($session_id) ? false : true;
}

We found this when running install.php and got this message:

A common misconfiguration is that the 'session.save_path' directive is not pointing to a valid directory.

Please correct your PHP configuration in the php.ini file located here below.

/path/hidden/php5/php.ini


Perhaps someone in development can review.

Actually our error is a different than yours because we have the function defined. A simple fix in your case is to edit SugarApplication.php and change:

if(can_start_session()){
session_start();
}

to:

// if(can_start_session()){
session_start();
// }
