WP Http Error: cURL error 28: Connection timed out after 10001 milliseconds

I saw a previous fix to this error which said:

Please modify wp-config.php ( you can find this file in your root directory ), and before the line:
/* That’s all, stop editing! Happy blogging. */
add this line:
define(‘ALTERNATE_WP_CRON’ , true );
I hope that helps!

So I tried it, and it still gives me the same error plus, I now get a message that says:

Warning: Use of undefined constant ‘ALTERNATE_WP_CRON’ – assumed ‘‘ALTERNATE_WP_CRON’’ (this will throw an Error in a future version of PHP) in /hermes/walnacweb06/walnacweb06an/b44/eh.yogaconn/wordpress/wp-config.php on line 64
