Hi! in rev 10959 controller VirtueMartControllerVmplg member func pluginNotification calls the wrong member of vDispatcher https://dev.virtuemart.net/projects/virtuemart/repository/virtuemart/revisions/10959/diff/trunk/virtuemart/components/com_virtuemart/controllers/vmplg.php
vDispatcher::importPlugin('vmpayment'); should be vDispatcher::importVMPlugins('vmpayment');
Yes thank you. Your post was discussed the same day, we just missed to add a note for you. Fix in svn since 5.1
