Thanks Ray. So now I've got to adjust most of the pages in the admin section.
I've managed to correct some successfully but I'm stuck on 'rtm-properties-list.php' which uses a search behaviour. I've tried to adjust lines 10,16,17 and 18 referring to a page you corrected for me that also used a search behaviour but I must be incorrectly adjusting it. The page loads ok but the three buttons using the search behaviour causes error. plus the view all button is not working.
