 * Using PHP 7.3, WP and all plugins up to date:
 * PHP Warning: A non-numeric value encountered in /var/www/vhosts/example.com/httpdocs/
   wp-content/plugins/wp-crontrol/src/schedule.php on line 62
 * Tip: There is one time plan (sorry, translating German) called “tpm_interval”(
   TPM Token Refresh Interval) for which you report: Dieses Intervall ist kleiner
   als die Konstante WP_CRON_LOCK_TIMEOUT, die auf 60 gesetzt ist. Ereignisse, die
   es verwenden, werden möglicherweise nicht pünktlich ausgeführt. (This interval
   is smaller than the constant WP_CRON_LOCK_TIMEOUT, which is set to 60. Events
   that use it may not execute on time.)
 * And some events like “wpseo-reindex-links”, “aioseop_cron_check_remote_notices”
   and “itsec_purge_logs” for which you report that no action is registered. Perhaps
   the problem is in such irregular cases?
 * The error message comes quite often, so for now am deactivating WP Crontrol –
   after all, we only need it sometimes. But when we do, it’s really indispensible–
   many thanks, John!

 * Thanks for the report. This might be caused by a cron event that contains a non-
   numeric schedule.
 * I’ll take a look at the code there and see what might cause that warning.
