Hi. When I download a header in a subsite, an extra button image is created, but there is no sticker next to this button. Wp reports no errors.
If this button is selected, the front-end site displays no image header.
However, the header files are in /blog.dir/3/files/2011/11.
The theme is original (not a child theme), and its code has not changed.
I deactivated and reactivated the theme. No effect.
I disabled all plugins. No effect.
Only the header of the main site is working properly. The same image does not work on others.
It's very surprising to the default wp theme ... I really need help!
