Requirements.

Before installing Reward Loyalty, verify your server meets these requirements.

Server Requirements

Hardware Specifications

The initial installation is approximately 200 MB. The rest of your disk space is used by your database, uploaded images, log files, and update backups. Most hosting plans include more than enough storage.

PHP Extensions

Most hosting providers include these extensions by default. The installer verifies them during setup.

Required Extensions:

• BCMath (ext-bcmath)
• Ctype (ext-ctype)
• cURL (ext-curl)
• DOM (ext-dom)
• Exif (ext-exif)
• Fileinfo (ext-fileinfo)
• Filter (ext-filter)
• GD (ext-gd)
• Hash (ext-hash)
• Iconv (ext-iconv)
• Intl (ext-intl)
• JSON (ext-json)
• Libxml (ext-libxml)
• Mbstring (ext-mbstring)
• OpenSSL (ext-openssl)
• PCRE (ext-pcre)
• PDO (ext-pdo)
• PDO SQLite (ext-pdo_sqlite)
• Session (ext-session)
• Tokenizer (ext-tokenizer)
• XML (ext-xml)
• Zip (ext-zip)
• Zlib (ext-zlib)

Control Panel Compatibility

Recommended: cPanel

cPanel is the recommended control panel. It provides correct Apache configuration, PHP extension management, and file permissions out of the box. Most shared hosting providers include cPanel.

Other panels that work well:

• DirectAdmin — Straightforward Apache configuration, similar compatibility to cPanel
• CloudPanel — Modern, lightweight panel for VPS setups
• No panel (SSH only) — Works perfectly if you're comfortable managing Apache and PHP from the command line

Plesk: Use with Caution

Plesk works but has known configuration quirks that cause issues with updates and performance:

• PHP version mismatch: Plesk manages FPM and CLI PHP versions independently. If they don't match, updates may fail silently.
• Extension mismatch: Extensions enabled for FPM (web) may not be enabled for CLI (updates, cron), causing unexpected errors.
• Performance tuning: Plesk's default OPcache and PHP-FPM pool settings are often too conservative, leading to slow performance.

If you use Plesk, ensure PHP CLI and FPM use the same version with the same extensions enabled, and review the troubleshooting guides linked above.

Shared Hosting

Reward Loyalty works on shared hosting. Verify that proc_open and proc_close PHP functions are enabled. Some hosts disable these by default.

These functions are safe to enable. Reward Loyalty contains no unverified third-party code, and these functions are required for image processing.

One-Click Updates

Important: Dashboard updates and Install from Package use the exec() PHP function to apply updates automatically. Many shared hosting providers disable this function for security reasons.

If exec() is available: One-click updates work automatically from the admin dashboard. This is the recommended way to update.

If exec() is disabled: Use Manual File Replacement instead. Download the latest version, upload the files, and restore your data — no exec() required. The rest of the application works without exec(). Only the automated update feature needs it.

💡 Tip: Most VPS and dedicated servers allow exec() by default. If you're on shared hosting and your provider won't enable it, manual updates are a reliable alternative.

Production Requirements

HTTPS Certificate

An HTTPS certificate is required for production deployments. This enables:

• Secure connections for all users
• PWA features (offline access, home screen installation)
• Modern browser security features

Most hosting providers include free SSL certificates through Let's Encrypt. Contact your hosting provider if you need help enabling HTTPS.

💡 Note: For local development, http://localhost works without HTTPS. PWA features can be tested locally.
