Child Theme - Parents Costumizer Data


i created a website and adjusted it to my needs (Costum CSS/footer.php) Now i learned about the existence of child themes and im trying to create one.

I already downloaded the Sydney Child Theme from the aThemes Website and put it via ftp into the Themes folder. Now it appears in my Wordpress-Backend. Sadly when i load it in Live-Preview, doesnt have all the other adjustments i made in the costumizer (images/logo/costumCSS etc). I guess i have to put a line of code somewhere so it links to the parents theme data?

Help would be greatly appreciated! :))


Hello Tobias,

Each theme has its own options storage in database, including child themes.

It means that you will have to configure the theme once again after activating your child theme, it’s quite normal.

You can try to use Customizer Export/Import plugin.

Please remember about importance of regular full site backups (files and database):

Hi Roman,
thank you for the helpful advise and the links!
i have a backup-plugin up and running, and i manually exported the files from ftp and the database via phpmyAdmin yesterday to have extra security.

I will try the costumizer export/import and I will work my way through the Staging-Environment tutorial aswell, as soon as i have some spare time! thanks again!


You are welcome Tobias! And have a nice day :slight_smile:

Kind Regards, Roman.
