Hi,

I upgraded to rails 2.1. This in turn broke my active\_scaffolds plugin  
however, the AS team had a newer version that could handle 2.1

So I install that, and now I find a new error which seems unrelated to  
the AS issue.

I receive this message:

Code :

1. ArgumentError in CategoryController#index
2. 
3. Unknown key(s): count\_includes

What does this mean? Google will not tell me :-P.

Anyways, here is the full trace file (which I do not understand)

“count\_includes” is likely a method provided by AS. I’d post this  
error on their support forum.
