When I try to edit a checkout price rule that I created in 0.8.17240, I get this error:
Apply the rule only to cart items matching the following conditions (leave blank for all items)
Fatal error: Call to a member function getFrontendInput() on a non-object in /home/auth5t0/public_html/UK/app/code/core/Mage/CatalogRule/Model/Rule/Condition/Product.php on line 142
The rule is still working on the frontend, though.
I can’t see a way to delete it so I can start from scratch.
