I am trying to upload plugins/themes via the WordPress admin interface on a Multisite install.
I have checked the blogs.dir directory and it's permissions are 755 as required.
The error I am getting is:
Unable to create directory /var/www/wordpress/wp-content/blogs.dir/2/files/2012/05. Is its parent directory writable by the server?
If I login via SFTP, I cannot see anything under the /blogs.dir/ folder yet. Given i've added no content yet, that would seem ok however i'm not sure.
The folder is owned by me (root) however the other folders are owned by www-data. Could that be the issue?
