Warning: Invalid argument supplied for foreach() in db.php on line 263 oops

Hi hope someone can help me with this issue. http://iwebsite.ph/

I was able to successfully installed and setup wordpress multisite. I want to try multi-db right away instead of installing it later to make sure we have it setup.
I tried to install multi-db by following the instructions. I checked my phpMyAdmin and I see the new databases. But when I go to my website now I see an error message
Warning: Invalid argument supplied for foreach() in /home/kryz2per_vps/iwebsite.ph/wp-content/db.php on line 263
oops

Not sure what this means. Below is my db-config.php
Im on Virtual Private Server

173.236.148.220 is the IP on the DNS record wpmu.iwebsite.ph is the hostname

Thanks!
