[SOLVED] Problems with editing post title

First of all I want say Big Thanks for your amazing theme. I am newbie in this and now I try to investigate diferent possibilities...
I found strange behavior of theme. If I try to edit post title after publishing then nothing happens on web pages. In console, in database I see changed title. If I activate any other theme I see changed title on any pages. But if I return on Atahualpa I see old first nonedited post title again.
Suggestion?
I use Atahualpa 3.4.6, Wp2.9.2.
