Plesk for Windows Plesk for Linux kb: technical ABT: Group B

Applicable to:

  • Plesk For Linux
  • Plesk for Windows

Symptoms

When opening a website in a web-browser or installing a WordPress plugin/theme at Plesk > WordPress > example.com > Plugins/Themes, the WordPress plugin/theme references to a non-existent path and, as a result, fails due to open_basedir restiriction:

PLESK_INFO: open_basedir restriction in effect. File(/var/www/vhosts/example.com/public_html/wp-content/cache/wp-rocket/www.example.com/shop/index-https.html/index-https.html_gzip) is not within the allowed path(s): (/var/www/vhosts/example.com/:/tmp/) in /var/www/vhosts/example.com/public_html/wp-content/plugins/wp-rocket/inc/classes/Buffer/class-cache.php on line 96

Cause

The absolute path to the WordPress file is merged with the path to the plugin directory and, as a result, restricted by open_basedir PHP parameter.

Resolution

Contact the WordPress plugin/theme developer to fid out how to fix the path.

 

The solution below is an example of how the issue can be fixed. It may differ for different plugins and themes:

  1. Log in to Plesk.

  2. Go to Domains > example.com > File Manager.

  3. Edit the file mentioned in the error. In this example, the file is  ...\httpdocs\wp-includes\l10n.php.

  4. Find WP_PLUGIN_DIR and replace it with basename( dirname( __FILE__ ) ).
    Example:
    Original:

    CONFIG_TEXT: $path = WP_PLUGIN_DIR . '/' . trim( $plugin_rel_path, '/' );

    Modified:

    CONFIG_TEXT: $path = basename( dirname( __FILE__ ) );

  5. Save changes.

    Solved. First I have changed only open_basedir in Domain > example.com > PHP Settings. Now I I have Changed the open_basedir parameter in my .user.php also like  open_basedir="none"

     

    Now it is working fine

    Hi, so I am having the same issue:

    [22-Jul-2022 06:51:08 UTC] PHP Warning:  file_exists(): open_basedir restriction in effect. File(C:\inetpub\vhosts\.../wp-admin/admin.php) is not within the allowed path(s): (C:/Inetpub/vhosts/...;C:\windows\Temp\) in C:\inetpub\vhosts\...\httpdocs\wp-admin\menu-header.php on line 257

    I have done quite a few Wordpress sites, but this is the first time I have had this problem on any of them, but it is also the first client using plesk.

    What exactly am I supposed to do?

    I went to menu-header.php on line 257:

    && file_exists( WP_PLUGIN_DIR . "/$sub_file" )

    I am not exactly sure what I need to change. Please advise on what I need to change?
