Strange thing happening in admin and user menu when customize template

[tatty]

Ello !

I've just installed coppermine 1.4.4
I have another 2 galleries, but they're coppermine 1.3.5... I'm going to upgrade soon.

But when I finished editing the template and uploaded everything... one strange thing happened.
First, I can't change the language I see. I wanna change it to English and it keeps in Portuguese no matter how many times I change.
Second, I don't see the CONFIG in the admin menu... it simply doesn't show. I tried to figure out how to access the configuration, but strangely, when I tried to switch to user, it leaded me to the configuration page 

I was checking the theme.php of "classic" template and thought it so different of the other versions...
is there anything I can read or anything that can help me editing the templates in coppermine 1.4.4??

Thanks a lot!
