I don't know what happened but i have my Edit order which isn't working anymore... i have added a script called: performance

and now when i hit edit order that give me this url:
http://www.storeurl/store/MYADMINFOL...02&action=edit

at the end and bring me to my store main page.. i have uninstalled and install it again 3 times and still nothing.. the url look weird once i have uploaded the order.php in my admin folder?

Also i'm on 1.3.9 as i'm slowly upgrading my huge store..

don' t know what to do
