same problem

resolved: deactivate plugin NextGEN Gallery by Photocrati 2.0.33

he is activated, and this question did not resolved!

I resolved my problem, thanks all.

Thanks for concern! =) in future I will make Child_Theme, but now I’m interested in another question.

I know about Child_Themes and changes will be lost when WP is updated, but I think that Twenty Twelve will not be updated. Now I need decrease margins in header image.

no, I use and make changes in original theme
