No way to contact support

It works but there is no way to contact support for the free version. After installing the plugin my error log is full of the following error:

Fatal error: Uncaught DivisionByZeroError: Modulo by zero in /home/XXXX/wp-includes/cron.php:436Stack Trace1.wp_reschedule_event(1714377695, ‘gg_woo_feed_cor…’, ‘gg_woo_feed_upd…’, Array, true)/home/XXXX/wp-cron.php:1292.{main} thrown in /home/XXXX/wp-includes/cron.php on line 436
