please help: white blank page instead content for Configure site-wide settings page (administer/config/settings)

Hi all!

I upgrade on Drupal 4.7.5. and after about 2 days (I moved filesystem and DB to another hosting)
I wanted to change some settings on page
Configure site-wide settings (administer/config/settings)
But after click on this link in admin zone, I get white blank page :( (it is loaded after one second)
(I tried it in both browsers, Firefox and IE )

All other admin pages working fine.

I tried update web with update.php, disable all modules (except basic in default instalation), empty cache table in DB, but it does not help. I still cant get content of site-wide settings page.

Here are HTTP headers (it seems ok) what I get. Can you somebody help me with this problem? Some ideas?
Thanks a lot
