Remove the annoying “blog” slug attached to the main site in a wordpress multisite 3.5

This worked well in a wp multisite 3.5 environment

1. At blog site set Settings -> Permalinks -> Common Setting -> Default (Must select default only and don’t touch any thing, If you need to change category base, tag base set at Network Admin only)

2. At Network Admin -> Sites -> (root site) Permalink Sturcture -> /%category%/%post_id% (this is an example, put here whatever you want, for example if you prefer “/%postname%/ just put it”

That it will remove /blog slug
