Comment (by sanilagauri7):

 If you face an "Undefined index" notice in WordPress after theme
 installation, it signals an attempt to access a non-existent array index.
 To resolve.Ensure theme compatibility with your WordPress version. Keep
 WordPress and the theme up to date. Verify your server's PHP version.
 Temporarily deactivate plugins to identify any causing issues. Inspect the
 theme files for code attempting to access undefined array indexes. Enable
 WordPress debugging for more error details. Consider using a child theme
 for modifications. If issues persist, contact theme support for
 assistance.
