    I'm creating Gutenberg blocks using MB Blocks and Builder. Whenever I click on a block to edit it, I get this PHP error in the log. It only happens when MB User Meta or MB User Profile is enabled.

    Hi Drake,

    Something goes wrong with the function get_current_screen() and it does not return a screen object which always has the property id.

    Please try to edit the file /wp-content/plugins/metabox-meta-box-aio/vendor/meta-box/mb-user-meta/src/DuplicatedFields.php and check the object $screen on line 31, the code should be

    $screen = get_current_screen();
    if( ! is_object( $screen ) ) {
        return $html;

    Then clear the log and edit the block again. Let me know how it goes.

    That fixes the error.
