Modx 0.9.6.3 and PHP 5.3

PHP 5.3 has introduced a new error level that reports deprecated functions. On line 13 of the config file use this line instead:

error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED)

Retrieving Plesk FTP Users Names and Passwords for Specific Domain

The following query will retrieve the sub-domain name, ftp username, and ftp password for a specific domain.

SELECT CONCAT(CONCAT(s.name, '.'), d.name) AS subdomain, u.login, a.password FROM subdomains AS s
JOIN domains AS d ON s.dom_id=d.id
JOIN sys_users AS u ON s.sys_user_id=u.id
JOIN accounts AS a ON u.account_id=a.id
WHERE d.name='example.com'

If you want to see all subdomains, then omit the WHERE clause.

# yum install ImageMagick.x86_64

In the highly unlikely event that you ever, for whatever reason forget your password to log into Plesk, one way of recovering the password is by loging into the server via SSH.

# cat /etc/psa/.psa.shadow
