Question

I am currently working on a Magento store (ver. 1.6.2.0) however when i click on the url re-write management i get a Magento error page, below is the information from the Magento error log.

So far i have tried the following

1. Restoring the Mage.php file
2. Restoring index.php
3. Refreshing indexes and clearing cache
4. Deleting all data in catalog_url_rewrite table and reindexing

I would be grateful if someone could help me figure this out!

Answer 1

It turns out the error was being thrown at the walkAttributes('backend/afterLo...', Array) stage. I did an email each time it went to the function and it turned out an old plugin that needed updating installed an attribute as the system. So it was looking for a model that didn’t exist.
