# Child theme errors

 * [9 years, 5 months ago](https://wordpress.org/support/topic/child-theme-errors-4/)
 * By trying to create a child theme of Gatsby by the [Child Theme Configurator](https://wordpress.org/plugins/child-theme-configurator/)
   plugin the Analyzer of the plugin returns these errors:
 *     ```
       Notice:  Undefined variable: charset_collate in /home/httpd/vhosts/(client)/(domain)/wp-content/plugins/companion-auto-update/companion-auto-update.php on line 54
   
       Warning:  session_start(): Cannot send session cache limiter - headers already sent (output started at /home/httpd/vhosts/(client)/(domain)/wp-content/plugins/companion-auto-update/companion-auto-update.php:54) in /home/httpd/vhosts/(client)/(domain)/wp-content/plugins/ip2location-country-blocker/ip2location-country-blocker.php on line 824
       ```
   
 * The plugin says:
    “Please contact this Theme’s author and report the items inside
   the box above. You may or may not be able to use this Theme as a Child Theme 
   while these conditions exist. It is possible that this theme has specific requirements
   to work correctly as a child theme. Please make sure you are using the latest
   version of this theme and check your theme’s documentation for more information.”
 * Maybe you can use this information for further development.

 * the messages seem to come from the plugins [‘companion-auto-update’](https://wordpress.org/plugins/companion-auto-update/)
   and ‘[ip2location-country-blocker](https://wordpress.org/plugins/ip2location-country-blocker/)‘
   rather than from your theme.
 * try to temporarily deactivate these plugins and see if the child theme configurator
   returns any other error messages.

 * Thanks very much for your help, Michael.
    By deactivating all plugins except 
   the Child Theme Configurator it doesn’t return any errors.
 * I now posted it in the forum of the Companion Auto Update plugin:
