Question: A website hosted in Plesk is not accessible: open_basedir restriction in effect


Applicable to:

• Plesk for Linux
• Plesk for Windows

Symptoms

• A website is not accessible with one of the following errors in a web browser:

404 file not found
500 Internal Server Error
Error 500 move_uploaded_file(): open_basedir restriction in effect. File(/path/to/the/directory) is not within the allowed path(s): (/var/www/vhosts/example.com/:/tmp/)
No input file specified.

• The following error message appears in the domain's Logs page (Domains > example.com > Logs):

<...> open_basedir restriction in effect. File(/path/to/the/directory) is not within the allowed path(s) <...>
Uncaught Exception: Session: Configured save path '/path/to/the/directory' is not a directory, doesn't exist or cannot be created.

Cause

The PHP script is trying to access the folder for which access is not allowed. This restriction is defined by the PHP open_basedir variable for each domain separately. By default, open_basedir allows access to the tmp and domain's document root directories, as well as the system's default sessions path.


Resolution

1.Log in to Plesk.

2.Go to Domains > example.com > PHP Settings.

3.Add the path from the error message to the open_basedir field:

on Linux

Below is an example for the directory /path/to/the/directory:

{WEBSPACEROOT}{/}{:}{TMP}{/}{:}/path/to/the/directory

on Windows

Below is an example for the directory E:\path\to\the\directory\:

{WEBSPACEROOT}{/};{TMP};{/};"E:\path\to\the\directory\"
4.Apply the changes.

Note: The default session.save_path for Linux is (RedHat-based) /var/lib/php/session/ or (Debian-based) /var/lib/php/sessions/, and for Windows is C:\Windows\Temp
