Hello,
Recently I have upgraded my Magento from 1.9.0.0 to 1.9.1.0 and now the backend return a 404 error...
I have a "complex" structure for my website and I think the problem is related to my .htaccess.
Currently, to solve the problem, I have created a duplicate of app/code/local/Mage/Core/Model/Store.php and removed all index.php in URL.
The problem is that I can't use Magento Connect because it always ask me to login when I try to update, install or remove a module.
Suppose my website is http://example.com/
I have a magento running on http://example.com/ and a wordpress running on http://example.com/my-wordpress
My www-data structure is like this :
www-data/.htaccess (http://example.com point here and I use the .htacccess to redirect request to the good directory
www-data/magento
www-data/wordpress
www-data/magento/.htaccess
www-data/wordpress/.htaccess
