Hi,
It seem you have upgraded from VM 2.0.0 to VM 2.0.2 and the problem comes from the core and template modification when they make VM 2.0.2.
We've checking and fixing the upgrade problem for version Joomla 1.5. Then will send you the new modification.

(The OT KID version for Joomla 2.5 does not meet this problem and already come with VM 2.0.2. You can download and try. It is included in OT KID package).

Thanks
