I’ve had the same problem!
I contacted my host like Soulgirl had, but my host (Lycos) weren’t so helpful. Maybe it is something to do with them going out of business, i don’t know…
‘Please be informed that if the Word application is directly from WordPress, you would have to contact their support for further assistance.’
Anyway, i tried the Disable ‘Canonical Redirection’ Plugin and that seems to have worked!
