Apache reconfiguration fails in Plesk: Wrong variable to subsitute

Symptoms

• Apache configuration generation fails with the following or similar error:

  PLESK_ERROR: New configuration files for the Apache web server were not created due to the errors in configuration templates:
  Template processing failed: file = /opt/psa/admin/conf/templates/default/domainVhost.php, error = Template_Exception: [Template_Variable_Domain_PhysicalHosting] Wrong variable to subsitute: maintenanceMode file: /opt/psa/admin/plib/Template/Processor.php line: 27 code: 0 Previous error: Template_Exception: [Template_Variable_Domain_PhysicalHosting] Wrong variable to subsitute: maintenanceMode file: /opt/psa/admin/plib/Template/Processor.php line: 27 code: 0 Previous error: Template_Exception: [Template_Variable_Domain_PhysicalHosting] Wrong variable to subsitute: maintenanceMode file: /opt/psa/admin/plib/Template/Variable/Abstract.php line: 67 code: 0.

• Custom Apache virtual host templates are used:

  # ls -l /usr/local/psa/admin/conf/templates/custom/domain/
  -rw-r--r-- 1 root root 987 Jul 22 16:13 domainVhost.php

Cause

Custom Apache virtual host templates contain a syntax error or reference to a nonexistent variable. 

Resolution

1. Connect to the server using SSH.

2. Move the custom templates folder to another location:

   # mv -f /usr/local/psa/admin/conf/templates/custom /root/custom_templates/

3. Rebuild web server configuration files:

   For RHEL-based Linux distributions (CentOS, RedHat, CloudLinux):

   # /usr/local/psa/admin/sbin/httpdmng --reconfigure-all

   For Debian-based Linux distributions (Ubuntu, Debian):

   # /opt/psa/admin/sbin/httpdmng  --reconfigure-all

Note: Check Plesk Advanced Administration Guide to see the full list of allowed variables for custom virtual host templates.
