Warning: session_start(): open(/var/cpanel/php/sessions/alt-php* failed: No such file or directory

The error message you're seeing, "Warning: session_start(): open(/var/cpanel/PHP/sessions/alt-php* failed: No such file or directory", indicates that PHP is unable to start a session because it cannot find the directory to store session data.

Here's how you can address this issue:

  1. Create the Session Directory:

    Make sure the session directory exists. You can create it using the following command:

    bash

 

  • sudo mkdir -p /var/cpanel/php/sessions/alt-php*
  • Set Proper Permissions:

    Ensure that the directory has the correct permissions. It should be writable by the web server. You can set the appropriate permissions with the following command:

    bash
  • sudo chmod 1733 /var/cpanel/php/sessions/alt-php*

    This command sets the "sticky bit" which ensures that only the owner of a file can delete or rename it.

  • Verify Ownership:

    Confirm that the directory is owned by the correct user and group. In most cases, it should be owned by the web server user (e.g., apache, www-data, etc.):

    bash
  • sudo chown -R webserver-user:webserver-group /var/cpanel/php/sessions/alt-php*

    Replace webserver-user and webserver-group with the actual user and group used by your web server.

  • Restart the Web Server:

    After making these changes, you'll need to restart your web server for the changes to take effect. The command will vary depending on your server setup:

    • For Apache:

      bash
  • sudo service apache2 restart
  • For Nginx:

    bash
  • sudo service nginx restart
  • For LiteSpeed:

    bash

 

    • sudo service lsws restart
  1. Check for Typos in Session Configuration:

    Review your PHP configuration files (php.ini) to ensure there are no typos or errors in the session.save_path setting.

  2. Review PHP Handler Configuration:

    If you're using multiple PHP versions or handlers, ensure that the configurations are correctly set up in cPanel.

  3. Check for Disk Space Issues:

    Verify that there is enough disk space available on your server. If the disk is full, it can cause issues with file creation.

  4. Contact Hosting Provider or System Administrator:

    If the issue persists, consider reaching out to your hosting provider or system administrator for further assistance.

Always make sure you have backups available before making significant modifications to your server configuration.
