I've ran 4.7 with the starter kits and the blog mostly runs fine. In the Business Site template there is an issue with calling the wrong header place holder but it is an easy fix. I've not tried installing the package separately. Worse comes to worse could just install a starter kit with a blog and use that or package up the blog bits.

Hi Thang

Nope I haven't found a solution, so instead i just installed the uComment package and created my own blogsetup.
