We've recently upgraded to Umbraco Version 7.6.4 (assembly: 1.0.6396.36621).
Since the upgrade, I'm unable to Preview content (published or otherwise) using Internet Explorer 11.
When I click "Preview", an "Umbraco Canvas Designer" window opens at a white screen with a spinninig icon in the centre. LHS menu bar is partially loaded, however, no icons are present.
Issue persists on Windows 7 and Windows 10 machines running IE 11, even when running in IE Safe Mode with add-ons disabled.
The root cause was found to be the way in which we've defined implemented the Intranet Zone in Internet Explorer. Our website is similarly named and is falling into the Intranet Zone definition.
Umbraco Preview makes a call to an external site to download some files, however, the call fails because of the zone configuration.
Chrome, Firefox, Edge, etc all work because they don't have a concept of zones.
Hi Dane,
What was your solution to this issue? we are working on an intranet site, where the corporate browser is IE11 and we have the same issue.
The calls we see failing are javascript calls relating to isArray and jQuery.
The issue for us was related to Security Zones in Internet Explorer and our proxy script (if I recall correctly Chrome and Edge worked OK because they don't have the same security zone concept).
Our default domain policy pushed out by Group Policy was forcing everything ending in ourdomain .com.au to the "Intranet" security zone. Our proxy script was set to bypass the proxy for addresses ending in
When the default domain policy was disabled, ourdomain .com.au/umbraco uses the "Internet" security zone and therefore the proxy was able to download external internet content.
I hope this helps point you in the right direction.

Canvas designer previews loads fine in Chrome.
Has anyone encountered this before?
I was unable to reproduce this behaviour offsite using Windows 7 / IE 11.
It seems particular to something in our corporate SOE.
Still, any suggestions or advice would be appreciated.
The Fiddler trace below shows output of a preview attempt in Internet Explorer (top) vs Chrome (bottom.
Note the /umbraco/preview/undefined in Internet Explorer.
Chrome correctly calls /umbraco/dialogs/Preview.aspx?id=3234
If I manually enter http://www.xxxxxxxx.com/umbraco/dialogs/preview.aspx?id=3234 into Internet Explorer, the page redirects to http://www.xxxxxxxx.com/3234.aspx and the preview renders OK.
