Brief Description of Issue:
I have a copy of www.xcess.com in a VM
I unpacked PE 7.0.0.1585 upgrade package into the folder and ran the upgrade via a browser.
I log into the site as Host and Go Admin – Users and add a user. I get a MASSIVE error in the Add User pop up but the user is added

Clear Steps to Reproduce:

Step 1 - Create a NEW VM from the SKIN-TEMPLATE VM of your choice (Dev, Test, Stage)
Step 2 - Make yourself a member of the Windows Adminstrator Group (so you can update the old site with new files)
Step 3 - Hit the site in a browser on a VM and sign in (host1/dnnhost)
Step 4 - Navigate around make sure the pages are all accessible
Step 4 - Unpack the 7.0 PE upgrade zip to a named folder
Step 5 - Open the folder, select ALL, then copy
Step 6 - Open the site folder in the VM and copy across the files
Step 7 - Once the file copy is complete refresh the HOME page of the site
Step 8 - Log in to start the upgrade in the browser
Step 9 - Logged in as HOST go Host --> Host Settings --> Other Settings and turn on "Enable Users Online? "
Step 10 - Go Admin --> User Accounts
Step 11 - Click "Add New User" and add a new user

Actual Result:

Actual Result 1 - I get a massive error message in the UI:
