Same problem here.
Environment: Jenkins version 1.518, Publish Over CiFS version 0.2, Jenkins Server: Win 2003 Server
Seems like the configuration is not read correctly from the XML file:

Sorry, my bad. This is not really a duplicate, because it refers to CiFS configuration not SSH. It could still be a related issue though.
