Basic System Requirements for EventON
Last Updated: June 11, 2025
To ensure optimal performance of the EventON main plugin and its addons, your web server must meet the following technical requirements. These specifications vary depending on whether you are using the EventON main plugin alone, EventON with addons, or the specific combination of EventON, Tickets addon, and WooCommerce. Also depending on amount of events and event data, website traffic, and memory needs of other plugins in your website, may require higher than mentioned requirements from your website. What is mention below are general minimal conditions.
EventON Main Plugin (Only)
The following requirements apply to running the EventON main plugin on your WordPress site:
- WordPress Version: 6.0 or higher (latest stable version recommended)
- PHP Version: 8.0 or higher (PHP 8.1+ recommended for best performance)
- MySQL Version: 5.7 or higher, or MariaDB 10.3 or higher
- PHP Memory Limit: Minimum 128 MB (256 MB recommended)
- Web Server: Apache or Nginx
- SSL: HTTPS is strongly recommended for secure data handling
- Cron Jobs: WordPress cron (WP-Cron) must be enabled for scheduled events
- Permalinks: WordPress permalinks must be enabled for proper URL routing
- Browser Compatibility: Latest versions of Chrome, Firefox, or Safari for admin and front-end functionality
EventON with Addons
When using EventON with one or more addons (e.g., RSVP, Seats, or Bookings), the requirements are slightly higher due to increased functionality and database interactions:
- WordPress Version: 6.0 or higher (latest stable version recommended)
- PHP Version: 8.0 or higher (PHP 8.2+ recommended for optimal performance)
- MySQL Version: 5.7 or higher, or MariaDB 10.3 or higher
- PHP Memory Limit: Minimum 256 MB (512 MB recommended for multiple addons)
- Web Server: Apache or Nginx
- SSL: HTTPS is required for addons handling sensitive data (e.g., payments or user information)
- Cron Jobs: WordPress cron (WP-Cron) must be enabled, with server-side cron recommended for addons with recurring tasks
- Permalinks: WordPress permalinks must be enabled
- Browser Compatibility: Latest versions of Chrome, Firefox, or Safari
- Additional Notes:
- Some addons may require specific PHP extensions (e.g., mbstring, json, curl). Ensure these are enabled on your server.
- High-traffic sites or sites with many events may benefit from a hosting environment with opcode caching (e.g., OPcache) and object caching (e.g., Redis or Memcached).
EventON + Tickets Addon + Woocommerce
The combination of EventON, the Tickets addon, and WooCommerce significantly increases server demands due to complex database queries, ticketing functionality, and e-commerce processing. Slow load times can be mitigated by meeting the following requirements:
- WordPress Version: 6.0 or higher (latest stable version recommended)
- WooCommerce Version: 7.0 or higher (latest stable version recommended)
- PHP Version: 8.0 or higher (PHP 8.2+ strongly recommended for performance)
- MySQL Version: 8.0 or higher, or MariaDB 10.4 or higher
- PHP Memory Limit: Minimum 512 MB (768 MB or higher recommended to prevent memory exhaustion)
- Web Server: Apache or Nginx with sufficient resources (at least 2 CPU cores and 4 GB RAM for medium-traffic sites)
- SSL: HTTPS is required for secure payment processing
- Cron Jobs: Server-side cron is strongly recommended to handle ticketing and WooCommerce scheduled tasks efficiently
- Permalinks: WordPress permalinks must be enabled
- Browser Compatibility: Latest versions of Chrome, Firefox, or Safari
- PHP Extensions: Ensure mbstring, json, curl, gd, and imagick are enabled for WooCommerce and ticketing features
- Performance Optimization:
- Opcode Caching: Enable OPcache to improve PHP performance.
- Object Caching: Use Redis or Memcached to reduce database load, especially for high-traffic sites.
- Database Optimization: Regularly optimize your database to improve query performance. Consider InnoDB storage engine for better concurrency.
- CDN: Use a Content Delivery Network (CDN) for faster delivery of static assets (e.g., images, scripts).
- Hosting: A managed WordPress hosting plan or a VPS with at least 4 GB RAM is recommended for sites with heavy event and ticket sales activity.
- Important Notes:
- Slow loading times are often due to insufficient PHP memory or unoptimized database queries. Increasing the PHP memory limit to 768 MB and enabling object caching can significantly improve performance.
- Ensure your hosting provider supports high resource allocation for PHP processes, as shared hosting plans may struggle with this setup.
- Test your site with a performance tool (e.g., GTmetrix or Pingdom) to identify bottlenecks, especially if handling large numbers of events or tickets.
General Recommendations
- Backup: Always have a reliable backup system in place to protect your event and ticketing data.
- Staging Environment: Use a staging environment to test updates for WordPress, EventON, addons, and WooCommerce before applying them to your live site.
- Hosting: Choose a reputable hosting provider with scalable resources, especially for sites using the Tickets addon and WooCommerce.
If you need help verifying your server setup or optimizing your site, please consult your hosting provider.
