When we load our pages in XPM the browser console appears to be showing several 404s for resources:
http://localhost/SDL/Common/ApplicationHost/ApplicationHost/Views/Frame/cultures/frame.en-US.js?1.0.0.1253
I checked on the CMS server and there's only 6 non-English frame JS files, nothing for en-US.
A call from Editor_v7.1.0.66.10_.aspx seems to be looking for se_blank.html
returns 404.
We also have a couple of exceptions:
Uncaught SyntaxError: Unexpected token ILLEGAL
Tridion.Utils.Object.deserialize
Tridion.Utils.CrossDomainMessaging._messageHandler
f.executeListener
a
Uncaught ReferenceError: Invalid left-hand side in assignment
Tridion.Utils.Object.deserialize
Tridion.Utils.CrossDomainMessaging._messageHandler
f.executeListener
a
Is our installation just knackered?!?
UPDATE
So the se_blank.html appears to be normal XPM behaviour, but as our application is DD4T we need to handle that route.
