Routing & Events	Symfony Routing, Event Dispatcher
Database	Illuminate Database (Eloquent)
Templates	Twig 3
Search	Meilisearch (optional)
Cache	File / Redis
Storage	Local / AWS S3 (Flysystem)

Installation

MegaforBB v1.1.3 — the first stable release — is now available and ready to use.

Download the latest package from GitHub Releases.

1. Upload the files

Extract megaforbb-upload.zip from the release archive and upload it to your hosting account.

2. Import the database

Import the database from megaforbb-database.zip using phpMyAdmin or a similar tool.

No migrations required. The release includes a fully prepared database — just import it and you are good to go.

3. Configure the environment file

On your hosting, rename .env-simple to .env and edit its contents to match your website:

APP_NAME=MegaforBB APP_ENV=Production APP_DEBUG=false APP_URL=https://forum.example.com APP_KEY= # A strong random key APP_LOCALE=en APP_TIMEZONE=UTC DB_HOST=127.0.0.1 DB_DATABASE=forum_db DB_USERNAME=forum_user DB_PASSWORD=your_password CACHE_DRIVER=file # or redis SESSION_DRIVER=file MEILISEARCH_HOST=http://127.0.0.1:7700

Change the password immediately after your first login.

The admin panel is available at /admin by default (configurable via ADMIN_PATH).

Clear the application cache and your server's opcode cache after installation. You can also use Performance → Clear Cache in the admin panel.

That's it — MegaforBB is ready to use. Enjoy!

Optional: Cron job

For scheduled tasks (RSS imports, scheduled topics, etc.), set up a cron job to run every 5 minutes:

Plugins

Plugins live in the Inc/Plugin/ directory. Each plugin follows this structure:

• plugin.json — metadata
• plugin.php — event listener definitions
• routes.php — optional routes
• views/ — Twig templates

Built-in example: AI Auto Reply — automatically generates replies to newly opened topics via an AI assistant user.

Data Import

From the admin panel, you can import data from:

• XenForo
• MyBB
• MegaforBB (from another installation)

Import runs step by step; progress is tracked in the panel.

---

Development

Install dependencies for a development environment:

composer install

Optional dev tools:

composer require --dev squizlabs/php_codesniffer friendsofphp/php-cs-fixer phpstan/phpstan

With APP_DEBUG=true, errors are shown in detail via Whoops. In production, use APP_DEBUG=false; errors are written to Content/storage/logs/.

For upgrades or custom setups, migrations can be run manually:

php Forecor/bin/migrate.php php Forecor/bin/migrate.php --status
