Blocky child:Item account not registered or doesn’t have a view.php file.

The page header right side: Item account not registered or doesn’t have a view.php file.

After installed Health Check & Troubleshooting, I found out the theme has a problem. Cause if we switched to other theme, the error is dissappeared.

I don’t want to change the theme, so How can I resolve this?

Thank you
