OK! That seems to have done the trick. Ummm.. Have you considered adding some instruction on the plugin page about the presence of a new Blog Categories menu item under the group Manage menu? How would someone know to go there and select the associated category otherwise?
This does answer the question I would have asked regarding how the group posts are associated with a category! Please consider explaining this on your plugin page.
Thanks! – Mark
