This is a good thing in production environments because it avoids potential security issues, but it can also be annoying when you’re trying to debug something.

Instead of displaying the errors, you can configure PHP to log them and then use the logs for debugging. For a Linux environment, you’ll need to create a file named vhost.conf inside the domain’s conf directory, /var/www/vhosts/domain.name/conf.


<Directory /var/www/vhosts/domain.name>
php_value error_log /var/www/vhosts/domain.name/statistics/logs/php-errors.log
php_flag display_errors off
php_value error_reporting 6143
php_flag log_errors on
</Directory>

Then create the file and assign it the right permissions


cd /var/www/vhosts/domain.name/statistics/logs/
touch php-errors.log
chown apache php-errors.log

And the last thing is to tell Apache to reread the updated conf file


/usr/local/psa/admin/sbin/websrvmng -a

It creates a service and configures iptables to block all traffic to the node (except the ports you specify), but allow all traffic through to the containers, so that they can manage their own firewall. It also allows the container’s firewalls to be managed on the node through a simple config file.

For qmail, you just need to create /var/qmail/control/smtproutes and enter “:yourmailserver.com”, then restart. Make sure the spam filter is configured to allow the mail server to relay through it.

This KB explains how to manually add extra FTP accounts that are restricted to their home directory.
