Firstly, I'd like to apologise if I've posted this question in the wrong forum area.
Basically, I've recently bought a co.uk domain via 123-Reg. I have configured things so that everything works okay when my domain is entered without the www (e.g. domain.co.uk on its own) and my blog appears without any problems.
However, I'd like my WordPress blog to appear if I typed the FULL domain itself, e.g. http://www.domain.co.uk. I cannot seem to do this. When I enter the full address, I arrive at a screen which reads 'This domain has been registered for a 123-reg customer'.
I have done a little digging and have discovered that WordPress automatically removes the www from the address bar. I was wondering whether there was a way that I could enter my full domain (complete with preceding www) and arrive at the same page as I do had I entered just the domain.co.uk.
I have checked with the domain provider and can confirm that I have a three year ownership of the full (www included) domain. Any advice/guidance would be most welcomed and I hope I have explained my problem in an understandable way!
