How would one go about debugging this further?

回答1:

Check if the php version is correct, to know PHP version your Apache server is using use phpinfo(),php version check but you might get a different version in php -v. if that is the issue use

    $ sudo a2dismod php5.6
    $ sudo a2enmod php7.1
    $ sudo service apache2 restart

To switch php versions and then goto bootstrap/cache folder and clear the folder.

回答2:

Your laravel.log file has only root lavel write permission, however it seems your webserver using www-data as a group and maybe a user too. You can change group and owner of laravel.log file.

chown  www-data:www-data /home/forge/bheng/storage/logs/laravel.log

after this it will start logging.

For file permission in Laravel 5 you can check this How to set up File Permissions for Laravel 5 (and others)
