  • yes, i use custom theme by themeforest, and also used another extension that then I deleted a few days ago – themich Feb 23 '15 at 13:28

You have an attribute (product or category) that has a backend model that's not valid.

Run this query on the database to see the attribute:

SELECT * FROM eav_attribute where backend_model = 'fileattributes/attribute_backend_file';

If you don't need the attribute(s) that result from there, you can delete them, but backup your db first.

You have create an eav attribute which backend module is fileattributes/attribute_backend_file.This Attribute may be Dropdown or Multiselct. You need delete this attribute because it Backend Model Class donot not exits.that why is create issue.Just delete from eav_attibute table
