Architecture

MegaforBB runs on the Forecor hybrid kernel:

Request → public/index.php (Front Controller) → Forecor\Core\Application → Symfony DI (ContainerBuilder + auto-wiring) → Symfony Router & Event Dispatcher → Illuminate Eloquent ORM (database) → Twig (themes) + App layer (controllers / services / models) 

Requirements

Optional (recommended for production):

• Redis — cache and sessions
• Meilisearch — full-text search
• Varnish — HTTP cache layer

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=MegaforBBAPP_ENV=ProductionAPP_DEBUG=falseAPP_URL=https://forum.example.comAPP_KEY=# A strong random keyAPP_LOCALE=enAPP_TIMEZONE=UTCDB_HOST=127.0.0.1DB_DATABASE=forum_dbDB_USERNAME=forum_userDB_PASSWORD=your_passwordCACHE_DRIVER=file# or redisSESSION_DRIVER=fileMEILISEARCH_HOST=http://127.0.0.1:7700

4. Default admin credentials

Change the password immediately after your first login.

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

5. Clear the cache

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:

*/5 **** php /path/to/forum/public/cron.php

You can also trigger cron from the Cronjobs section in the admin panel.

Themes

MegaforBB ships with three ready-made frontend themes:

Themes can be activated and customized from the admin panel.

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

Update Check

MegaforBB checks version.json daily via cron. The current version and file manifest are read from this URL.
