Hi,
I think I was using wordpress.org 3.1.4 when this all happened.
I logged into my dashboard and saw there were some general plugin updates available and also a wordpress update.
I clicked on the update wordpress now button (rather than download it) and my google chrome screen semi-circle began to turn.
The next thing that happened I was directed to a blank page which had my blog address at the top http://www.robertfdrummond.com
I have tried a few things since then, including a Bluehost restore but I get a blank page for my blog and when I try to login to admin.
All help and ideas gratefully recieved.
Thanks,
Roebrt
