• In Plesk for Windows, the following error message appears in domain's error logfile %plesk_vhosts%example.com\logs\php_errors\example.com\php_error.log:

  CONFIG_TEXT: PHP Warning: Unknown: open_basedir restriction in effect. File(E:\custom_folder\sessions) is not within the allowed path(s): (C:/inetpub/vhosts/example.com\;C:\Windows\Temp\) in Unknown on line 0

In some cases:

• The phpinfo() page launched at Domains > example.com > PHP Settings > View the phpinfo() page is not accessible:

  PLESK_ERROR: Unable to retrieve information about the PHP configuration

• Logfile size quickly increases:

  # find /var/www/vhosts/system -size +1G -exec ls -lh {} \;
  -rw-r--r-- 2 root root 218G 1. Jun 11:27 /var/www/vhosts/system/example.com/logs/error_log

Cause

PHP script is trying to access the folder for which access is not allowed. This restriction is limited by the PHP open_basedir variable for each virtual host separately. By default, open_basedir is set to allows access for PHP files to the tmp and httpdocs directories.

Resolution

Note: If you are a domain owner and the open_basedir setting is not available for you, please contact your service provider for assistance.

Adjust the value of open_basedir in order to include missing path from the error message:

1. In Plesk, go to Domains > example.com > PHP Settings.

2. Modify the value of open_basedir:

   • For Linux

     Below is an example of including the directory /var/lib/php/session to open_basedir:

     CONFIG_TEXT: {WEBSPACEROOT}{/}{:}{TMP}{/}{:}/var/lib/php/session

   • For Windows

     Below is an example of including the directory E:\custom_folder\sessions to open_basedir :

     CONFIG_TEXT: {WEBSPACEROOT}{/};{TMP};{/};"E:\custom_folder\sessions\"
