I am having problems with editing sub-pages (nested pages) e.g. Home - Sub-page1 - Sub-Sub-page 1. Most of the time when you try to expand out the pages (clicking + sign ) nothing appears. Pages are still there. Clicking on the "Site Content" tab sometimes causes the pages to re-appear but this is also not consistent. I had this problem in Ver 2.2.2 , upgraded to Ver 2.3 and am still having the problem. This problems exists in IE7 , Firefox and Chrome. It is a major nuisance when you are in editing mode as you cannot guarantee content being accessible.
Any help appreciated.
