Syntax Error - after updating WordPress


after WordPress 4.9.3 my page shows an error. Theme has not been edited, everything is via child-theme. In it functions.php is empty.

Can you help me where can be a mistake?

Thank you

I don’t see such warnings on my local Sydney install with enabled WP_DEBUG. You can make a full site backup and try to reinstall the theme.

Also you can disable WP_DEBUG on your production website and recreate your website in a staging environment or locally for testing and troubleshooting purposes.

Here are helpful tutorials:
