Plesk for Linux kb: technical

Applicable to:

  • Plesk for Linux

Symptoms

  • Unable to log in to Plesk: Plesk login page is returned in a browser without any errors or warnings

  • When uploading a file via Plesk File Manager, one of the following error messages appears:

    PLESK_ERROR: The file "picture.jpg" is too big. Try to upload this file via FTP.

    PLESK_ERROR: No upload response

  • Cannot upload files in applications, e.g WordPress, Joomla, etc:

    PLESK_INFO: The uploaded file exceeds the upload_max_filesize directive in php.ini

  • Extension update fails, e.g Joomla:

    CONFIG_TEXT: An error has occurred uploading this file to the server.
    The maximum allowed size of PHP to upload files is too low: This is configured from the PHP directives 'upload_max_filesize' and 'post_max_size' (locatable and configurable in your file 'php.ini' or '.htaccess').
    Unable to find the installation package

  • In some cases, the following error messages might appear in /usr/local/psa/admin/logs/panel.log:

    CONFIG_TEXT: PHP Warning: POST Content-Length of 90378782 bytes exceeds the limit of 67108864 bytes in Unknown on line 0
    ERR (3) [panel]: Forgery protection token check failed.
    ERR (3) [panel]: Permission denied.#0

Cause

Low values of directives post_max_size and upload_max_filesize is specified either in Plesk php.ini or in the domain settings.

Resolution

Change the necessary values

On server-wide level

  1. Connect to the server via SSH

  2. Open the file /usr/local/psa/admin/conf/php.ini in a text editor and specify limits for post_max_size and upload_max_file size in bytes.

    Note: The default value is 2147483647 (2GB):

    # egrep 'post_max_size|upload_max_filesize' /usr/local/psa/admin/conf/php.ini
    post_max_size = 2147483647
    upload_max_filesize = 2147483647

  3. Restart the psa service:

    # service psa restart

  4. Log out from Plesk UI and Log in again to apply changes.

For a specific domain
  1. Log into Plesk
  2. Go to Domains > example.com > PHP Settings
  3. Adjust upload_max_filesize and post_max_size values:
    PHP Settings
  4. Click the OK button

    Hello @Laurent,

    As I can see this issue is sometimes resolved by executing the following command, could you try to execute it:

    plesk installer --select-release-current --reinstall-patch --upgrade-installed-components

    Hi! To change those settings you need to contact your hosting provider and ask either to set the required values on their side or grant you permission to edit the settings on your side by modifying the service plan.
