I've got a major issue with chameleon that I'm unable to figure out for some time now..

Firstly, to be able to understand this say I've got the following rules configured:

1. Main TLD Rule - mydomain.net (this is the joomla installation domain)
2. Sub Domain Site Rule - site1.mydomain.net
3. Another Main TLD Rule - customtld.com (this is a additional website Alias)

So my problem is whenever I use a New TLD (Top Level Domain) name like (no3) instead of the sub domain (no2) then I'm unable to register or login and most of the times it just shows no2 or no1's homepage on no3. So when I try to click on register or login the page just refreshes and does nothing.

But this doesn't happen when I use sub domains? (like with no2). Just with new TLD's (no3).

So I tried to include another test sub domain with rule 3's contents (like: www.customtld.com, customtld.com, test.mydomain.net) then when I go there everything works I can login and register and homepage is perfect!

I tested this with multiple domains and sub-domains and I get this result every time.

Have anyone ever got this same issues before?

Can someone please help me.
I've got Joomla 2.5

Your help will be much appreciated!
Thanks.
