.load() fails and then refreshes the page

Hello. I have problem like in topic.
Code is here:
http://maxadrenaline.pl/new/

I tried to load for ex. google.com but it's not working either.

I used this func before and there was no problem, but I seriously dont know what's the problem here?
I tried /index.php, index.php, full adress like http://.../index.php but none of them work.

Can someone tell me what is causing this?

Thanks in advance and sorry for my english.
