    Hi @merlin1764,

    Sorry for the inconvenience caused to you.

    I have read your support query. As per your query it seems that there is some conflict with other plugins or theme. Please deactivate other plugins and theme one by one and check which plugin causes the issue.

    Thank you

    @sanjaydabhoya I have the same issue on a site, disabled all other plugins and still the same.

    PHP Warning: session_start(): Cannot start session when headers already sent in /var/www/vhosts/DOMAIN/wp-content/plugins/user-blocker/includes/user_blocker_common_functions.php on line 510

    We use Hello theme on that site.

    Here is the quick fix. Please do it and let us know if still getting issue.
    at wp-content/plugins/user-blocker/includes/user_blocker_common_functions.php on line 510,
    just replace
    if (session_id() == ”) {
    with
    if (!headers_sent() && session_id() == ”) {

    Hi there,

    we had the same issue. This is the fix that worked for us. Please update your plugin now.

    user-blocker\includes\user_blocker_common_functions.php

    /**
    * Start session if not started
    */
    if (!function_exists(‘ublk_session_start’)) {

    function ublk_session_start() {
    if (session_id() == ” && !headers_sent()) {
    session_start([‘read_and_close’ => true]);
    }
    }

    }
