WP_CRON_LOCK_TIMEOUT

Hello

My site broke down (error 500) after several manipulations on the .htaccess and the deactivation of the plugins I finally managed to relaunch my website. This pendant I have a message that appears on the top of the page of my website:

Deprecated: a? without parentheses? BC ? d: e<code>is obsolete. Use either</code>(a ? b : c) ? d: e<code>or</code>a? b:(c?d:e)

in /home/webmane/www/wp-content/themes/shapely/inc/extras.php at line 442

Note: WP_CRON_LOCK_TIMEOUT constant already defined in /home/webmane/www/wp-config.php at line 86

I don’t know how to fix this`
