Why does Magento indexing not work, saying “Invalid backend model specified”?

Symptoms:

  • Index rebuilding in Magento 1.4.2.0 did not work.
  • When trying to update the index “Product Flat Data” via the Magento backend’s index management function, this error message is shown:

    Invalid backend model specified: catalog/product_attribute_backend_boolean

Solution:

This can be fixed by directly editing database content: go to table eav_attribute and edit all records where column backend_model contains catalog/product_attribute_backend_boolean. Normally, it is only in the record for attribute gift_message_available. Simply completely delete that backend_model value, as it is unclear yet what belongs there. (It would have to be looked up in a fresh Magento 1.4.2.0 installation).
