creating child theme problem

I am trying to create a child theme for Roseta using Child Theme Configurator. I got this message:

Notice: Constant WP_CRON_LOCK_TIMEOUT already defined in /home/username/public_html/wp-config.php on line 91

Notice: Constant AUTOSAVE_INTERVAL already defined in /home/username/public_html/wp-config.php on line 92

Notice: Constant WP_POST_REVISIONS already defined in /home/username/public_html/wp-config.php on line 93

Notice: Constant EMPTY_TRASH_DAYS already defined in /home/username/public_html/wp-config.php on line 94

At some point, someone put this in the “auto-install” version of WordPress used by your hosting provider. They supposedly help “optimize” wordpress, but do just the opposite when they are implemented incorrectly.

Unless you are running in debug mode, these notices will not affect the front-end, but will continue to be logged until resolved.

To correct this issue, you will need to manually edit wp-config.php (you have to use FTP or your hosting account file manager) and either:

comment out or delete the constant definitions.
move the definition statements so they appear BEFORE the final require statement as shown below:
If moving:

// >>>> SHOULD GO HERE!!! <<<<

/* That's all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
        define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php’);

// >>>> NOT HERE!!! <<<<

If commenting out:

Locate the lines that begin with “define” that correspond to the error notice, and type “//“ before it, e.g.,

// define( ‘WP_CRON_LOCK_TIMEOUT', 60 );
