Do you have any non-bundled plugins installed? If so, try disabling them one by one. If the problem goes away, you know that it is caused by one of the plugins.

Thanks @juko.jaakkola for your answer. I must say, im an idiot.
I have Widget Manager plugin installed http://community.elgg.org/plugins/384604/4.7/widget-manager
It has an option to override default page, and i have not checked it.

Well, this will be here for information if somebody have this issue sometime.
Thanks again for you FAST answer, you rule!
