PyroCMS error - Undefined Property

I have created a site with Pyro on my local server which is running fine.

I've put it onto a staging server and it's throwing an error in model.php in the Codeigniter system.

Severity: Notice

Message: Undefined property: Pages::$session

Filename: core/Model.php

Line Number: 50

At line 50 is

function __get($key)
{
    $CI =& get_instance(); //50
    return $CI->$key;
}

In the PHP error log though, it logs

Call to a member function set_flashdata() on a non-object in /var/www/vhosts/site/httpdocs/system/pyrocms/modules/modules/models/module_m.php

The full output of the debug is below

I don't know if this is a config issue on the server but these are core files which I've not changed.

Any ideas?

Solution

  • Looks like a PyroCMS bug in some early versions that should have since been fixed. Upgrade perhaps?

    EDIT: the bug is occuring because the session variable is somehow not being set. I'd look for differences between the application/config/config.php and application/config/autoload.php files on the local server and the staging server: they must somehow handle the session setup differently.
