My OMV virtualbox install has gone to sh*t. It kept complaining that it couldn't log in to vboxweb something or other, so I uninstalled the plugin hoping to reinstall, but now I get:
Failed to execute XPath query '/config/services/virtualbox'.
It's just error after error after error with this thing. I can't even dismiss this error. I should have know better than to trust a f-----g PHP project. It's fallen apart like a house of cards, as PHP always does....
