This is the error I am getting.....  Everything seems to work on the front side but the admin side of the products gives an error if I try to edit a product.  So.... It doesn’t work very well.  Any help would be great.

Can you tell me if you re-indexed after you did your upgrade?

i don\’t know if its right or not. but i fixed this by deleting backend models (catalog/product_attribute_backend_boolean) in the \"eav_attribute\" table column name \"backend_model\".
even after deleting this one it will come up with another invalid backend, i had to delete the backend values of about 3 or 4 attributes than it all got ok.
hope it helps and its not wrong smile
