Hi,I was working on my site in the CMS and all was ok. I created a page off a top level child page in  the root as a secondary child page then the entire site structure in the Left handside of the CMS disappeared so all I can see now is Home (which has a little green plus in the Home icon) and the recycle bin. When I click on home to extend the child nodes nothing happens. I can now see a Child Items tab when I click on the home icon - this is ok but I cant see any lower child pages of these items.How can I get my CMS back to its original state where I can see the nodes on the lefthandside tree structure?ThanksJon
