Required PHP Extensions

Ensure the following PHP modules are enabled on your server:

• ext-curl: Required for license validation, Quantum Randomizer API calls, and external webhooks.
• ext-json: Used for ticket storage, cart payloads, and instant win tables.
• ext-mbstring: For multibyte character and language handling.
• ext-openssl: For secure communication and cryptographic random integer generation.

Server & Cron Configuration

• Server Cron (crontab): Standard WordPress virtual cron depends on site traffic. For accurate countdown endings, ticket releases, and auto-draws, set up a real server cron job firing every minute:

  * * * * * wget -q -O - https://yourdomain.com/wp-cron.php >/dev/null 2>&1

• Object Cache (Optional but Recommended):
  • Redis or Memcached via a persistent object cache drop-in (object-cache.php) provides massive speed improvements for high-traffic ticket selection.
