Requirements

System requirements for Burst Statistics v3.3.0.

---

Server Requirements

Requirement	Minimum
WordPress	6.4
PHP	8.0

---

WordPress

Burst Statistics requires WordPress 6.4 or higher. The plugin hooks into plugins_loaded (priority 1 and 9) and relies on the WordPress options API, cron API, REST API, and $wpdb for database access.

---

PHP

Burst Statistics requires PHP 8.0 or higher.

caution

If the active PHP version is incompatible and the plugin fails to bootstrap, Burst catches the error and stores it in the following options:

Option	Content
burst_php_error_time	Unix timestamp of the last error
burst_php_error_count	Cumulative error count
burst_php_error_detected	Concatenated error messages (newline-separated)

An admin notice is then shown in the WordPress dashboard:

Urgent action required
Burst can not load due to the following error: …

Resolve the underlying PHP issue to clear this notice.

Free and Pro Compatibility

When both the free and the pro plugin are present, a compatibility layer (class-compatibility.php) ensures no class conflicts occur during the transition. The BURST singleton class is only defined once, regardless of which plugin file loads first:

if ( ! class_exists( 'BURST' ) ) {
    class BURST {
        public static $instance;

        public static function instance(): BURST {
            if ( ! isset( self::$instance ) && ! ( self::$instance instanceof BURST ) ) {
                self::$instance = new BURST();
            }
            return self::$instance;
        }
    }
}

This guard means it is safe to have both plugins present simultaneously during an upgrade; the free plugin is deactivated automatically once pro is active.

Database

Burst Statistics creates and manages 11 custom database tables on activation and upgrade. All tables are prefixed with the site's configured $wpdb->prefix and are created using dbDelta() via WordPress's upgrade API.

Table	Purpose
burst_statistics	Raw visitor page-view records
burst_sessions	Session-level data
burst_goals	Goal definitions
burst_goal_statistics	Goal conversion records
burst_browsers	Browser lookup table
burst_browser_versions	Browser version lookup table
burst_platforms	OS/platform lookup table
burst_devices	Device-type lookup table
burst_referrers	Referrer URL storage
burst_known_uids	Unique visitor UID tracking
burst_query_stats	Search query statistics

No minimum MySQL or MariaDB version is enforced in code beyond what WordPress itself requires.

---

Multisite

Burst Statistics is a per-site plugin. On WordPress Multisite networks it must be activated at the individual site level. Network activation is not supported unless you have confirmed compatibility with your specific network configuration.

---

Constants

The following PHP constants are available after plugins_loaded fires. They can be used to detect the plugin's presence and version in custom code.

Constant	Type	Description
BURST_VERSION	string	Current plugin version (3.3.0)
BURST_PRO	bool	true when the pro plugin is active; undefined otherwise
BURST_FILE	string	Absolute path to the active plugin's main file
BURST_PATH	string	Absolute path to the plugin directory (trailing slash)
BURST_URL	string	Full URL to the plugin directory
BURST_PLUGIN	string	Plugin basename (e.g. burst-pro/burst-pro.php)
BURST_PLUGIN_NAME	string	Display name: Burst Pro or Burst Statistics

caution

The lowercase aliases burst_version and burst_pro are deprecated and kept only for backward compatibility. Do not use them in new code.
