Hi, I got this error message :

Warning: array_map(): Argument #2 should be an array in /home/www/piwik/core/Log.php on line 274

I temporarily fixed it by replacing

// set the log writers
        $logWriters = $logConfig[self::LOG_WRITERS_CONFIG_OPTION];```

with

// set the log writers
$logConfig['log_writers'] = array('screen');
$logWriters = $logConfig[self::LOG_WRITERS_CONFIG_OPTION];```

in file : core/Log.php
It seems $logConfig['log_writers'] is not set anywhere
