My Magento site (1.5) has a problem after import. I can't enter the products page in the admin (can't edit the products) and some products have lost their size options (nothing on the drop down menu).
I need to recover this.
When I try to enter the product editing page, I get :
There has been an error processing your request
Source model "catalog/entity_product_attribute_design_options_container" not found for attribute "options_container".
So basically, I want to be able to edit my products, and on frontend to chose the size in the drop down menu
