bbPress 论坛在 2.5.12 和 2.5.13 版本 如果服务器升级到 PHP 7.1 版本，打开版块链接的时候回出现以下错误。

[31-Jul-2017 08:12:42 UTC] PHP Fatal error:  Uncaught Error: [] operator not supported for strings in /home/user/public_html/wp-content/plugins/bbpress/includes/forums/functions.php:1800

解决方法要么是升级到 2.6 版本，要么就是修改下 functions.php 文件的 1800 行。

测试了下还是修改 functions.php 文件的 1800 行比较简单靠谱。使用 PHP 7.1 。通过改变行 1800 来修改它，以将数值转换为数组。

修改后如下

if ( empty( $post_stati ) ) {
            $post_stati = (array) bbp_get_public_status_id();

测试可正常使用。
