Theme Horse

Hi Grafixer,
Yes exactly you need to create a new functions.php file inside thee clean retina pro child folder.I am not sure how the header image is lost? If i found any solution regarding to the header image lost then i will let you know.

You can use any of this method to import the style.

@import url(“../clean-retina-pro/style.css”);
The above code only import the css. Other that this you need code customization inside functions.php

Thank you!
