Error: No Matching Admin User Found

Funniest thing. I am able to provisioning a new site with WHMCS on WP but not without errors. I keep getting "No Matching Admin User Found"

Then i try to run it again and the error changes to "Mapped domain already exists for nautical.ebizlynx.com:"

So clearly the sites are being created and WHMCS is able to connect to WP.

Trouble is, WHMCS will never run the module and mark the order as complete... it gets stuck on pending.

Please advise,
