After upgrading to 1.6.0 my homepage doesn’t work anymore,
only the header is there, no footer, no columns, ... just this error message
Fatal error: Call to a member function getBackend() on a non-object in
/home/ ... /app/code/core/Mage/Eav/Model/Entity/Abstract.php on line 816
I’ve seen other sites (while searching to fix it) with the same message on their homepage.
How can I fix this please?
