There was a thread on this, but it is closed:

I realized I have one site that still has this problem when attempting to access the attribute cotroller page. I posted in the previous thread where I fixed the problem when it happened trying to access categories, but it's not fixing it here.

Is there another file I need to modify on this cart to fix it for attribute controller?

BTW, it's a REALLY old cart that I REALLY don't want to have to upgrade. (1.2.2)
