Hi Ivan,
Thanks for getting in touch.
The domain with issues is; martialartsrecovery.com.au
As an update I have managed to get back to the WP login page with the cookies error.
I have also amended changes I had previously made to the hosts file while I was developing the new theme. This change has not affected anything so far.
I believe the issue may have something to do with the ‘multisite’/WPMU I was using while customising the new template.
I have read that inserting the following code into the config.php may help although I haven’t tried this yet;
define(‘ADMIN_COOKIE_PATH’,’/’);
define(‘COOKIE_DOMAIN’,”);
define(‘COOKIEPATH’,”);
define(‘SITECOOKIEPATH’,”);

I look forward to hearing your thoughts.
Thanks
