Ok, we had a site at http://www.manchestercommunitychoir.org.uk, hosted by a company called Fasthosts. And until yesterday the domain's nameservers pointed to the Fasthosts nameservers. After a few attempts, I managed to update the domain's nameservers to wordpress. And when I saw that WHOIS had seen the updated nameservers, from the WordPress dashboard I made manchestercommunitychoir.org.uk my primary domain.
I expected that typing (www.)manchestercommunitychoir.org.uk into the address bar would take me to the WordPress home page. But it doesn't, it takes me to the home page of the 'old' site hosted by Fasthosts. When I type manchestercommunitychoir.org.uk/join in the address bar, it takes me to http://manchestercommunitychoir.org.uk/joining-2/ which is a page on the WordPress site. From there, if I click on Home, I go back to the home page of the site on Fasthosts!
I haven't altered anything on the Fasthosts Control Panel, where the Advanced DNS option lists 11 A records as well as a MX record. But what I have done is copied some of those A records and the MX record to the WordPress DNS records (Store/Domains/Edit DNS).
I thought the A records which I copied were all associated with email, which is still being hosted by Fasthosts.
I'm sure I've missed a step somewhere, or misunderstood some terminology, and done the wrong thing. Can you help me sort this out please.
