Initial Multisite WP install, domain mapping

Hello All,

Hoping I can get some help here. I've installed my initial wp multi site install. everything is working fine... so far.. I've also installed the domain mapping plugin, in hopes of fixing an issue, i can't seem to figure out.

i'm updating my main site and it's updating, but all pages/links go to this page...

i'm hoping to install different sites I manage on to on multisite wp platform. here is a screen shot attached..

can anyone let me know what I'm doing wrong?

Your help is greatly appreciated.
