url takes me to domain host not site

Your site loads fine for me, as does wp-admin. You may want to try clearing your browser cache, and trying again. It could also be a DNS issue for you. It looks like 123-reg directs new domains to a parking page on registration.

I’ve tried clearing cache, cookies, rebooted my computer, tried it in both IE and Firefox and on a completely different laptop. Nope fix the problem.
When I type the host address (https://mpostlethwaite.danpostlethwaite.com/#page) I get this https://s40.photobucket.com/albums/e203/matthewp1992/?action=view&current=site.jpg
Then when I click anything on there it takes me to 123-reg again

Try contacting your hosts for assistance.

My host is my brother and he doesn’t know what’s wrong either.
Is there any other way of logging into your blog admin dashboard without going through mpossdesign.co.uk/wp-login or wp-admin?

Have you actually pointed your new domain to your hosted site?

Its suddenly decided to work again. I tried mpostlethwaite.danpostlethwaite.com/#page again and it took me to the full site. If I use https://www.mpossdesign.co.uk it takes me to the site, but mpossdesign.co.uk still takes me to 123-reg.
ah well, iv saved a bookmark so it should work from now on, thanks for the help any way

Looks like a DNS issue possibly. I notice your domain was last updated yesterday. Give it some time, and the non-www version should work as well ??

Yeah it was only set up yesterday. I just found it strange that it was only computers in my house that wasn’t allowing it
