I deleted a website instance via the Magento Backend. Since then I get this error:
Recoverable Error: Argument 1 passed to Mage_Core_Model_Store::setWebsite() must be an instance of Mage_Core_Model_Website, null given
I already deleted everything in the var/cache folder and also executed this query without success:
SET FOREIGN_KEY_CHECKS=0; UPDATE `core_store` SET store_id = 0 WHERE code='admin'; UPDATE `core_store_group` SET group_id = 0 WHERE name='Default'; UPDATE `core_website` SET website_id = 0 WHERE code='admin'; UPDATE `customer_group` SET customer_group_id = 0 WHERE customer_group_code='NOT LOGGED IN'; SET FOREIGN_KEY_CHECKS=1;
app/etc/use_cache.ser is not existent.
Do you have any advice how to get rid of the above mentioned error?
