我在WordPress中使用了BB press插件来创建论坛。我已经能够列出论坛主题，但当我点击论坛主题时，我收到以下错误：
Fatal error: Uncaught Error: [] operator not supported for strings in C:\xampp\htdocs\wordpress\wp-content\plugins\bbpress\includes\forums\functions.php:1800 Stack trace: #0 C:\xampp\htdocs\wordpress\wp-includes\class-wp-hook.php(298): bbp_pre_get_posts_normalize_forum_visibility(Object(WP_Query)) #1 C:\xampp\htdocs\wordpress\wp-includes\class-wp-hook.php(323): WP_Hook->apply_filters('', Array) #2 C:\xampp\htdocs\wordpress\wp-includes\plugin.php(515): WP_Hook->do_action(Array) #3 C:\xampp\htdocs\wordpress\wp-includes\class-wp-query.php(1681): do_action_ref_array('pre_get_posts', Array) #4 C:\xampp\htdocs\wordpress\wp-includes\class-wp-query.php(3238): WP_Query->get_posts() #5 C:\xampp\htdocs\wordpress\wp-includes\class-wp.php(617): WP_Query->query(Array) #6 C:\xampp\htdocs\wordpress\wp-includes\class-wp.php(735): WP->query_posts() #7 C:\xampp\htdocs\wordpress\wp-includes\functions.php(955): WP->main('') #8 C:\xampp\htdocs\wordpress\wp-blog-header.php(16): wp() #9 C:\xampp\htdocs\wordpress\index.php(17): require('C:\\xampp in C:\xampp\htdocs\wordpress\wp-content\plugins\bbpress\includes\forums\functions.php on line 1800
我无法找出根本原因。请建议

原因是与PHP7.1不兼容，如果你恢复到PHP7.0它将起作用... 有一个bbPress测试版可以解决这些问题，但现在恢复到PHP7.0将是更稳定的解决方案。
