When an item is published, and you wish to edit it, you must retract it first.

To retract a photo or a review you will need to find the list of options at the top right hand side of the screen. These include: actions, display, add and state. They are in a green band than runs along the top of the item (article, photo, blog).

State is the one you are interested in. If an article (review) or a photo is published it will read as follows, state: published. To the right of the word 'published' there is a small green arrow. Select that and the drop down screen will present you with the option to 'retract' the item.

Once the item is 'retracted' the edit tab will appear and you may edit the item as you did when you first created it. Once you have finished editing, be sure to save the item and then submit it again to be published by editors.
