Problem with login form

Hello I am sorry for double post, but when I tried to click on the first, I was sent it automatically to another post.

I've installed this template on joomla 2.5.x and when I try to register/login I can not do that in firefox or chrome. When I open with Internet Explorer this form works.
The link is www.carte.nfc.ro . This is a test link.

If I used quickstart installation package register/login form works fine with any browser.

Who can help me to fix that problem.
