Can't translate any theme when child theme is activated

[cherrycoding]

Hey everybody,

I got a problem with my shop, I've created a very basic child theme from a bought theme and when I am activating this theme I am not able to translate any theme (parent, classic, ..)

I always get the error "the directory /var/cache/dev/themes/MyChild/translations/de-DE does not exist"

If I create this dir it's the same, so as I found it I am not the only one with this problem but I couldn't find any fix.

Can anyone help me please?

Thanks

Regards

Alex
