To support the expanded use of Websockets for additional dynamic pages within the Submitty website, we must remove a restriction on a specific php function.

Version v20.08.00 requires the following edits:

  1. Locate your php.ini file.

    It is probably something like /etc/php/8.1/fpm/php.ini.

    Note: You can run this command to print your specific version of php:

    php -r 'print PHP_MAJOR_VERSION.".".PHP_MINOR_VERSION."\n";'

  2. Edit this file:
    Remove stream_socket_client from the list of disabled_functions.
    Save the file.

  3. Restart php fpm:

    sudo systemctl restart php8.1-fpm

    Or more generally:

    sudo systemctl restart php$(php -r 'print PHP_MAJOR_VERSION.".".PHP_MINOR_VERSION;')-fpm
