I solved the problem. I was almost right, the only issue I forgot about was to declare php in the beginning

<?php

define( 'HEADER_IMAGE_WIDTH', apply_filters( 'twentyten_header_image_width', 940 ) );
	define( 'HEADER_IMAGE_HEIGHT', apply_filters( 'twentyten_header_image_height', 614 ) );

Now it works.

Sorry, try to remember…it is because I really old)))

Dear esmi, thank you very much!

It works(exept IE, of course)!

I remember your previous advice and experiment with my child_2010.

I felt that somthing is wrong with that margin: -240px
I removed it and one column stood correct.
But the sidebar went wrong!!!

That CSS is quite simple: just moves sidebar region from right to left!

#container {
float:right;
margin:0 -240px 0 0;
width:100%;
}

#primary, #secondary {
float:left;
overflow:hidden;
width:220px;
}

Thanks to all, I have created a new child theme and changed css. It works!

Thanks to all, I am in process of changing…

Thank you very much, it works!

I modified header.php like this <div id="site-description"><a href="https://www.mysite.com"><?php bloginfo( 'description' ); ?></a></div>
It works both in main and in child theme. Now I need to copy the modified file to child theme catalogue?

Thanks a lot! I managed to create a child theme with another style.css file.

But this problem can be solved not with help of css. I guess I need to change the data in my database. Please,advise how to proceed!
