Warnings with php8.x

Hi,

we did a server upgrade for our “older” application. While most of the code works fine with php 8.x I get some error’s in your plugin. I fixed it for now with some validations, but these fixes are gone after the next update.

// if ($comment->comment_approved === "0") {
// Warning: Attempt to read property "comment_approved" on string in /home/bim/domain.nl/current/wp-content/plugins/wpdiscuz/utils/class.WpdiscuzHelper.php on line 1407
if (empty($comment->comment_approved)) { // added by OL
    return true;
}

// Warning: Attempt to read property "comment_ID" on string in /home/bim/domain.nl/current/wp-content/plugins/wpdiscuz/class.WpdiscuzCore.php on line 893
if (isset($commentListArgs["lastCommentIdInList"])) { // added by OL
    $commentListArgs["lastCommentIdInList"] = $commentList[$count - 1]->comment_ID;
}
