Features: - Scan for all WordPress installations on server - Disable wp-cron for specific domain, user, or server-wide - Check wp-cron status for any domain or user - Automatic wp-config.php backups before changes - Intelligent cron job staggering to prevent load spikes Load Distribution: - Staggers cron times across 15-minute windows - Example with 300 sites: distributes across minutes 0-14 - Site 1: runs at 0,15,30,45 - Site 2: runs at 1,16,31,46 - Site 3: runs at 2,17,32,47 - ...continues up to minute 14, then wraps - Prevents all sites from running simultaneously - Uses user crontabs (not system cron) for proper permissions Technical Details: - Adds DISABLE_WP_CRON to wp-config.php - Creates user-specific crontab entries - Prevents duplicate cron jobs - Shows cron timing when adding jobs - Handles multiple WP installations per user
