Been helping Kim_Possible troubleshoot this strange error she's been getting while trying to run her mod through the MPV:

[ FAIL ] ip_admin_only_v100/subsilver2.xml: Invalid XML/MODX

Element '{http://www.phpbb.com/mods/xml/modx-1.2.1.xsd}mod': No matching global declaration available for the validation root.

Turns out she had the date on one of her history entries as "2008-11-3" and the date format should have been "2008-11-03". Error needs to be handled appropriately in MPV.
