Magento – All categories are disappeared in the menu

categoryerrormagento-1.7

Now I have a very big problem. All categories disappeared from my menu.

All categories are active. I tried to refresh the cache and reindex all index but it didn't work.

Any idea for my problem ?

Best Answer

Check whether new categories are shown
check whether the root category is still attached to the correct store view
check the SQL which is used to load the categories for the menu
check whether any rewrite for the menu is still there
check whether any core hack is still active
I think the categories are still in the backend, and in the correct order?

Magento – How to list all parent categories

This should get you the first level categories

$categories = Mage::getModel('catalog/category')->getCollection()
    ->addAttributeToSelect('*')//or you can just add some attributes
    ->addAttributeToFilter('level', 2)//2 is actually the first level
    ->addAttributeToFilter('is_active', 1)//if you want only active categories
;
