Wordpress install on add-on site redirecting to main site

[admin]

My main website is:

<a href="http://sandybeachit.co.uk" rel="nofollow noreferrer">http://sandybeachit.co.uk</a>

I have a wordpress site setup at my addon-domain:

[<a href="http://imadeitviral.com][1]" rel="nofollow noreferrer">http://imadeitviral.com][1]</a>

The wordpress site is in:

/hosting/imadeitviral

The above address can be found here on the primary site under sandybeachit.co.uk/hosting/imadeitviral/

I have got the site url and home set to "http:// imadeitviral.com" (without the space between "http:// and madeitviral.com"

But when you go imadeitviral.com the site attempts to load my primary site at sandybeachit.co.uk except the site does not load correctly, you can try it and your see what i mean.

If i set the wordpress site url and home to pointing to "sandybeachit.co.uk/hosting/imadeitviral" the site will load fine, so i know i have got something wrong, but i can not figure out what.

I have tried removing the .htaccess file in my main domain and editing it so i an sure its not that is the problem as well as the .htaccess file in the wordpress folder.

I did the install via Site Software Softaculous Apps Installer

Can i get some pointers as to what i have done wrong or missed ?

Thanks

After a little more testing:

What i am finding is if i goto:

imadeitviral.com/

The site loads

As soon as i go into:

imadeitviral.com/wp-admin

after a short while the site times out to a 404 with the message:

"Not Found

The requested URL /wp-admin/plugins.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
