I got the exact same issue as mentioned in this topic: Getting a sudden error on Magento backend / frontend

But i can't find any solution on the problem in the topic?

Hope anyone can help :).

This is the error message i get, when i try to enter 'category' in the backend:

    Invalid backend model specified: ultramegamenu/category_attribute_backend_grid_columns

Trace:

run this query on the db

SELECT * FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_grid_columns'

and remove all the rows you find.
Or you can simply delete them by running this code:

DELETE FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_grid_columns'

but it's a good idea to check first what you are deleting.

  • I tried to run the following command, and deleted the row in the db @Marius.

    code But now it says: Invalid backend model specified: ultramegamenu/category_attribute_backend_dropdown_blocks

    Trace: #0 /home/www/p196560/html/magento/app/code/core/Mage/Eav/Model/Entity/Attribute/Abstract.php(346): Mage::exception('Mage_Eav', 'Invalid backend...') #1 /home/www/p196560/html/magento/app/code/core/Mage/Eav/Model/Entity/Abstract.php(640): Mage_Eav_Model_Entity_Attribute_Abstract->getBackend()...`

  • Do the same thing for the new invalid model – Marius Oct 22 '15 at 18:15
  • So instead you want me to write:

    SELECT * FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_dropbown_blocks'

    and the same thing for deleting it?

    DELETE FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_dropdown_blocks'

    But i was wondering, dont the magento shop need this sql rows for later? Or are they being created again, when the magenta shop need it? @Marius

     – Grumme Oct 22 '15 at 18:20
  • I can't find anything when i try to search the DB for SELECT * FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_dropbown_blocks'.

    Is it the right thing i'm trying to look up @Marius? :)

     – Grumme Oct 22 '15 at 18:26
  • Those rows are leftovers from an extension that was uninstalled. Delete what you find. Backup the db just in case and clear the cache after each delete. – Marius Oct 22 '15 at 18:58
  • Okay thanks.

    But when i search for : SELECT * FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_backend_dropbown_blocks'

    In the DB, i doesn't find anything. Is it the correct line i use for searching? @Marius.

    The new error is:

    backend model specified: ultramegamenu/category_attribute_backend_dropdown_blocks Trace: #0 /home/www/p196560/html/magento/app/code/core/Mage/Eav/Model/Entity/Attribute/Abs‌​tract.php(346):

  • did you clear the cache? – Marius Oct 23 '15 at 06:56
  • Yes i have cleared the cache @Marius – Grumme Oct 23 '15 at 07:47
  • After i cleared the cache, i can see there is a new error code, any suggestions what to do @Magnus ? I can't find anything in the database if i try to look up: SELECT * FROM eav_attribute where backend_model = 'ultramegamenu/category_attribute_source_dropdown_type'

    New error code `There has been an error processing your request Source model "ultramegamenu/category_attribute_source_dropdown_type" ikke fundet for egenskaben "umm_dd_type"

     – Grumme Oct 23 '15 at 12:08
  • the new error message says something about the Source model. So look for SELECT * FROM eav_attribute where source_model = 'ultramegamenu/category_attribute_source_dropdown_type' – Marius Oct 23 '15 at 12:21
  • Thanks a lot. I now deleted the db files, but now when i press categories, i just meets a blank page. Any suggestions @Marius :)? – Grumme Oct 23 '15 at 12:42
