Why not install WP in /blog ? This will save you miles of pain.
Because if I do that, when users navigate to domain.com/blog they would access the regular wordpress blog, instead of the integrated wordpress page in Magento, which the Integration extension offers.
I managed to fix this issue, I changed the Site Url to the root folder instead of the blog one, and it works.
However, I now have other problems with the multisite extension. Should I write about them here or should I open another thread?
Thanks
