Hello Mustafa,
Using 6.5.0.f 2014041803 and latest httpd.
In kloxomr panel, I have www. force redirect to www.
In DNS, I have wildcard CNAME for * ---> @.
Any subdomain other than CNAME www, as it is configured, does not point to the @ ---> IP.
The http request is redirected by kloxomr panel to a non-existent domain page i.e. default page.
Thats wrong.
