The exact issue I had was that the panel bar was showing the group pages. It has been quite a while since I delt with this problem but I believe it was solved by adding am item databound event (OnItemDataBound="RadPanelbar1_ItemDataBound")
to the sitepanelbar and calling this function:
public void RadPanelbar1_ItemDataBound(object sender, RadPanelBarEventArgs e)
CmsSiteMapNode node = e.Item.DataItem as CmsSiteMapNode;
if (node != null && node.PageType == CmsPageType.Group)
I hope this helps!
