django 1.5 update ALLOWED_HOSTS failing SuspiciousOperation
Resolved. I had deploy settings in a different file overriding the allowed_hosts in settings.py. Appologies missed this before posting. Thanks for the responses received.
I have updated to django 1.5 and am getting the following message:

SuspiciousOperation: Invalid HTTP_HOST header (you may need to set ALLOWED_HOSTS): localhost:8000

I have tried localhost, 127.0.0.1, localhost:8000 in ALLOWED_HOSTS. I have also tried ['*'] all without success.
Anybody any ideas where I am going wrong? Works as expected with DEBUG=False
