I have used the network admin for each site like this to set a image upload folder:
Network -> Sites -> Edit -> Settings
Upload Path wp-content/uploads
Fileupload Url http://www.mydomain.com/wp-content/uploads
But some sites are still uploading to blogs.dir (blogs.dir folders do not have the right permissions since I moved to a new server).
How do I set /wp-content/uploads as the default image folder for all sites?
