Invalid backend model specified: catalog/product_attribute_backend_sku
Invalid backend model specified: catalog/product_attribute_backend_sku : I got this error when i was trying to fix this issue Invalid backend model specified: catalog/attribute_backend_customlayoutupdate . I tried a lot of google search but did not get any result after that i jumped in to digging so here we goes .
I find the solution here , the main database table is responsible for is eav_attribute so i backuped the original eav_attributedbak using phpmyadmin and created and new table with fields by copying the sql from a virgin magento eav_attribute table .BOOM its working Awesome .
