Bit of clarity on why my Mac Mini and Powerbook could access the Community when nobody else could. I have 75ztcommunity.co.uk in my hosts file, no need for dns in that config. That was curve ball not remembering same .I spent some hours barking up various wrong trees. It was 16 years since I set up the forum and added site to hosts.
For anybody that's interested. Mac OS
/etc/hosts
add line, ip address and url of desired destination.
Overrides dns and maps to a new Internet Protocol (IP) address.
Very useful when setting up a new website for testing purposes without submitting to a dns service. Once all works properly and you are satisfied. You can then submit your website name and ip address to a service such as dnsexit so public can access your site via their Name Servers.
Oh what fun we have.
