Versions affected
General Information
This pertains only to Joomla! version(s): 3.5.0 and higher
What is the cause
A mass refactoring of the session library in Joomla 3.5.0 for future stability broke some old CLI scripts
How to fix
Ensure that you call the session initialise method with:
$session->initialise()ensuring that the first parameter is a JInput object (which should be retrievable from the application or you can create a new one). For more information please read the method documentation at https://github.com/joomla/joomla-cms/blob/3.5.0/libraries/joomla/session/session.php#L464
