Upload Child theme

Hi Guys,

I have a problem to install the child theme since the last update.
It didn´t work to upload directly from wordpress so i tried it via filezilla, but
it seems that the installed parent theme will not be recognized.
When i have a look at the appearance -> themes there is following error message:
The following themes are installed but incomplete.
The parent theme is missing. Please install the “enfold” parent theme.

After searching a few hours i couldn´t find any solution for it..
Would be so glad if you could help me with this :)

Thanks in advance!
