Cannot get Multi-DB to work with my multisite

I've created the 16 databases and I've tried over and over again to get Multi-DB to work with the inspire.vision site.

Something is amiss, though, and I don't know what. When I complete the procedure as per the Multi-DB instructions, the entire network simply stops working.

Would it be possible for someone to have a look and help me out with this?

Thank you,
Alex
