Creating child theme problem

Are you creating the child in themes folder not in twentyten folder

yes. the folders structure is:

themes
twentyten
Quanties
style.css

oh, it removed the spaces. ?? once more:

themes
   twentyten
   Quanties
      style.css

Why not copy n paste style.css unto yr new child theme folder. At the moment one style.css is importing another style.css .its a loop……

so do what i suggest and delete the import statement

You have import wrong

@import url('../twentyten/style.css');
this what you have it should be

@import url("../twentyten/style.css");

no, it is not the mistake. no matter if i use single quotes or double quotes, the problem still remains. it must appear somewhere during theme activation.
1. if twentyten is active and my child is in the list of available themes, everything looks ok and the theme twentyten works perfectly on my site quantummind.howto.cz.

2. when i try to activate the child theme, error message appears and the admin panel is unable to display info from the style.css header – author, files folder etc.

3. and this is how the folders structure looks and the whole contents of my style.css: https://www.ulozto.cz/6914637/03-jpg

SOLVED! ??

have fun…….

Most of the documentation shows the import url incorrectly…. glad I found your comment! Mine is working now. Only the custom header image isn’t showing up.

Ok, just uploaded the image…. all working now.
