Symptoms

• Statistics is not calculated by the daily webstat task. Errors similar to the following are found in %plesk_dir%admin\logs\php_error.log:

  PLESK_INFO: The system cannot find the file specified. (Error code 2)

• The %plesk_vhosts%example.com\logs\iis\W3SVC33\web_stat_executor.conf file has Webalizer configured as web statistics engine for example.com:

  PS Get-Content $env:plesk_vhosts\example.com\logs\IIS*\web_stat_executor.conf | Select-String "webstat type"
  <config><domain name="example.com" webspaceName="example.com" default_doc=""><webstat type="webalizer"/><alias
  name="example.com"/><alias name="www.example.com"/></domain></config>

• Webalizer is not installed, as can be seen in Tools & Settings > Server Components.

• WebalizerPath does not exist as a registry property in HKLM:\SOFTWARE\WOW6432Node\PLESK\PSA Config\Config\:

  PS Get-ItemProperty 'HKLM:\SOFTWARE\WOW6432Node\PLESK\PSA Config\Config' WebalizerPath
  Get-ItemProperty : Property WebalizerPath does not exist at path HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PLESK\PSA

Cause

Webalizer remains as the web statistics engine in a website configuration even after removal. It is a known Plesk bug with ID PPPM-9887, which is planned to be fixed in one of the future product updates.

Resolution

Force configure all domains to use AWStats:

1. Connect to the server via RDP.

2. Run PowerShell as Administrator and execute the following query:

   PS plesk db -Ne"select name from domains where htype='vrt_hst'" | % { if ($_) { plesk bin site -u $_ -webstat awstats } }

3. Wait for the daily job to execute again or use the instructions from one of the following articles:
