It's a small thing, but confused me. I was just re-starting working with CI again, and I followed the comments on "autoload.php" @ Line 107, which is :
| $autoload['model'] = array('model1', 'model2');
and I tried many times write my module name in small letetr as mentioned on the comments but failed. and finally I tried to make it Model and it works .
So, I hope you can change these 'model1', 'model2' WITH 'Model1', 'Model2'
It may be trivial, but at same time it may help others.
