It looks like you are not getting the iRite instances to appear in the admin area. Were you originally able to edit these parts of the pages? If so then the problem is likely one from making edits to the site or the globals file. Have you ensured that you have uploaded the iRite folder to your site? This will need to be in the root of the site that the PowerStore is in. Also you will need to ensure that you have the globals file properly set for the editors to appear. Do you get this same result when you are testing locally or only on your live site?
