    Hello,

    Once upgrading to PHP 8, we encountered a fatal error because of using this function:

    add_filter( 'post_class', 'um_add_restricted_class_css', 10, 1 );

    function um_add_restricted_class_css($classes){
    global $post;
    $restriction = get_post_meta( $post->ID, 'um_content_restriction', true );

    // if the post is restricted do this.
    if ( $restriction['_um_accessible'] == 2 ){
        $classes[] = 'um-restricted-content';
    }

    return $classes;
    }

    Can you please advise?

    Thank you,

    Dan

    You can try with this update

    if ( isset( $restriction['_um_accessible']) && $restriction['_um_accessible'] == 2 ){

    Thanks, this works.

    Is this related to PHP 8 syntax?

    Yes, you can’t access an element of an array
    without first testing if it’s an existing element
    then you can test if the element’s value is equal to 2.
