I am an MCT and whilst demoing your http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Accordion/Accordion.aspx page in IE6 I got the above error message.

 I have googled it and got many threads but no reason as to why your site is failing.  Is there a fix for this at the Client end, a patch for proxy server or something, or is it a problem at your server end?

 I cannot see how I can recommend Ajax as a way forward if this problem cannot been resolved....

 Cheers

Tom

Hi Tom,

As far as I know, Accordion works properly on IE6.  So I suspect that maybe you have installed some add-ons or plug-ins.  Please do the following,

1. Check whether other AJAX Controls work or not.  If all these control doesn't work, you'd better check if javascript is forbidden on your browser.
2. Please press Ctrl + F5 to refresh the page.
3. Check the plug-ins if you have installed.

If all these don't work, please feel free to let me know.

Best regards,

Jonathan
