Hi,
replace Categories_model or Categories with MCats.
I'm also reading the manual "Professional CodeIgniter" and I had to modify the file mcats.php, the Model master class in CI_Model and now runs fine.

[eluser]antoniog[/eluser]
Set this:

Code:

$autoload['model'] = array('MProducts', 'MCats');

That has nothing to do with it all the code is for CI 1.7.2

Code:

// all models and controllers need this code changes!
orderby = order_by
getwhere = get_where
etc!
Controller = CI_Controller
Model = CI_Model
etc

Want me to go on?

There are lots of errors in the view files also...

Plus there are lots of other errors in the code that needs to be fixed!

It does not use CodeIgniters Shopping Cart Class...
