I'm not sure if this is the right place to ask. The page I have problem is http://www.albezuta.com/admin/ModifyItinerary.aspx Basically, the user can use this page to edit an xml file which is the data source of an accordion control on another page. Everything works smoothly on my local developing computer, but very slow after I uploaded to the Winhost server, and the Delete buttons seem not working. Since it's a practice project of mine, I'll post the code here if it's necessary. Any help would be greatly appreciated.
