Seeing the WHMCS Client Page...but, Links Go Nowhere

Just like the title says...I'm seeing the WHMCS client page...but, when I click on any of the links- they just refreshes the page.

Before I installed Multisite Provisioning and Domain Mapping...it was working fine. Afterwards, no dice so far...just a page refresh.

Here's a sample; link it's spitting out...
