I tried to change my theme to child theme.
I went to this page and downloaded the file: http://docs.athemes.com/article/232-child-theme-for-sydney.
Then I went to install the child theme zip-file. It didn’t, work got this text (translated by google translate):
“The theme of the host was not found. You must install the host betheme theme before installing this theme.
Theme updated successfully.”
Whats wrong? My site is www.tool.net.ee
