I have installed 1.5.1.0 with sample data 1.6.1.0.

at front-end when i m clicking on Add To Cart button then error is coming up “Invalid backend model specified: catalog/product_attribute_backend_msrp”.

as well as in admin panel, “Product Prices & Category Flat Data” indexes are not reindexing… showing status as “processing”

so what is the actual problem? please…

A complete reinstallation of Magento 1.4.2.0 from scratch, not taking over the current content of the database. This was done in the case referred to here, as the shop was in testing mode still.

Probably, this could be fixed by directly editing database content, in analogy to a fix for a similar error: go to table

eav_attribute
and edit all records where column backend_model contains
catalog/attribute_backend_customlayoutupdate
.

Which normally is one record, or two if you use a localization package. Simply completely delete that

backend_model
value, as it is unclear what belongs there.
