Hi all,
During upgrade Magento Enterprise from 1.12 to 1.14.0.1 I got this problem when edit and save product in backend, so I can not edit an exist product.
It is working fine when you create new product or duplicate the exist one. After spend some hour to research, I found some helpful information here but it doesnt work for me. So I looking in log and trying to fix myself.
And finaly I got it fixed by this change:
Open this file /app/code/core/Mage/Adminhtml/controllers/Catalog/ProductController.php
Go to line 727 you will see like this (before change):
Add this line $product->setUrlKey(false); it will avoid url_rewrite checker before Save product.
I hope this help someone to solved your same problem.
