 * Dear Kharis,
 * I am facing the same problem/error message with a custom child theme derived 
   from your great theme Sydney. You can access the website at [https://www.jano-filder.de/](https://www.jano-filder.de/).
 * With CSS I moved the main content 100px down, so that there is currently no overlay
   between menu and content. But with my smartphone the main menu doesn’t work at
   all.
 * Thank you
