hello, i am afraid this does not come from opc, but i can locate the underlying system that prints this error. i suggest to:
- disable all plugins in joomla plugin manager that you do not use (especially unused payment and shipping plugins)
- you can try full text search for the "checkoutData" within *.php files at opc utils section (if it's supported on your server)
if this still does not help, i'd need to debug the messageQueue (JFactory::getApplication()->getMessageQueue()) to see where it shows. I'd start with opc view at /components/com_onepage/overrides/virtuemart.cart.cart.view.html (and see if this comes before, after or during the execution)
best regards, stan
