    Hello!
    There is a conflict with the WP Cerber Security.

    In Cerber – Console – Session’s tab.

    There has been a critical error on this website. Please check your site admin email inbox for instructions.

    `AH01071: Got error ‘PHP message: PHP Fatal error: Uncaught TypeError: unserialize(): Argument #1 ($data) must be of type string, array given in /wp-content/plugins/wp-cerber/cerber-common.php:4196\nStack trace:\n#0 /wp-content/plugins/wp-cerber/cerber-common.php(4196): unserialize()\n#1 /wp-content/plugins/wp-cerber/admin/cerber-dashboard.php(589): crb_unserialize()\n#2 /wp-content/plugins/wp-cerber/admin/cerber-users.php(1139): cerber_get_ip_info()\n#3

    Hi there,

    Seems the error was caused by the “unserialize” function in Cerber code.

    File: wp-content/plugins/wp-cerber/cerber-common.php
    Line: 4196

    Please edit that file and replace “unserialize” with “maybe_unserialize”

    Original code:

    function crb_unserialize( &$string ) {
    if ( PHP_VERSION_ID >= 70000 ) {
        return @unserialize( $string, [ 'allowed_classes' => false ] );
    }

    return @unserialize( $string );
}

    Fixed code:

    function crb_unserialize( &$string ) {
    if ( PHP_VERSION_ID >= 70000 ) {
        return @maybe_unserialize( $string, [ 'allowed_classes' => false ] );
    }

    return @maybe_unserialize( $string );
}

    Or you may try the fix from this repo:
    https://github.com/nawawi/wp-cerber.

    For clarification, Composer is not a framework, it is a PHP package manager and Docket Cache uses the Symfony components, not a framework.

    Thanks.
