Config File
===========

You can customize the default settings of Kanboard by adding a file `config.php` at the project root or in the `data` folder.
You can also rename the file `config.default.php` to `config.php` and change the desired values.

Enable/Disable debug mode
-------------------------

```php
define('DEBUG', true);
define('LOG_DRIVER', 'file'); // Other drivers are: syslog, stdout, stderr or file

// By default, the log file is in data/debug.log but you can change the path:
define('LOG_FILE', '/path/to/debug.log');
```

The log driver must be defined if you enable the debug mode.
The debug mode logs all SQL queries and the time taken to generate pages.

Plugins
-------

Plugin folder:

```php
define('PLUGINS_DIR', 'data/plugins');
```

Enable/disable plugin installation from the user interface:

```php
define('PLUGIN_INSTALLER', true); // Default is true
```

Change default plugin directory URL:

```php
define('PLUGIN_API_URL', 'https://kanboard.org/plugins.json');
```

Folder for uploaded files
-------------------------

```php
define('FILES_DIR', 'data/files');
```

Cache parameters
----------------

```php
// Available cache drivers are "file" and "memory"
define('CACHE_DRIVER', 'memory');

// Cache folder to use if cache driver is "file" (must be writeable by the web server user)
define('CACHE_DIR', DATA_DIR.DIRECTORY_SEPARATOR.'cache');
```

Enable/disable url rewrite
--------------------------

```php
define('ENABLE_URL_REWRITE', false);
```

```php
// Enable/disable email configuration from the user interface
