PHP allow_url_fopen don''t work

  • Hello, I'm sorry if I don't write in right place, but I want I ask how to activate option!
    I go in admin panel and on every website I mark "YES" on option Can edit the PHP allow_url_fopen configuration option in PHP Setting on domain edit menu, but in my installed website with Joomla, in Joomla admin panel continues to say:

    • The PHP allow_url_fopen setting is disabled. This setting must be enabled for the updater to work.
