如果我没有激活的调试模式，我在后端看不到任何媒体（在“媒体”菜单中，甚至在后期编辑器中创建的库中）。打开调试模式时：

define(\'WP_DEBUG\', true);

// Enable Debug logging to the /wp-content/debug.log file
define(\'WP_DEBUG_LOG\', true);

// Disable display of errors and warnings
define(\'WP_DEBUG_DISPLAY\', false);
@ini_set(\'display_errors\',0);if ( !defined(\'ABSPATH\') )
    define(\'ABSPATH\', dirname(__FILE__) . \'/\');

我有以下错误。但是系统文件插件。php在第992行左右结束。有什么想法可以导致这个问题以及如何解决它？非常感谢，这是我的自定义主题。

看起来这部分有问题：

//remove from menu
function remove_posts_menu() {
    remove_menu_page(\'edit.php\');
    remove_menu_page(\'edit.php?post_type=page\');
    remove_menu_page(\'edit-comments.php\' );
}
add_action(\'admin_init\', \'remove_posts_menu\');

//remove from menu
function remove_posts_menu() {
    remove_menu_page(\'edit.php\');
    remove_menu_page(\'edit.php?post_type=page\');
    remove_menu_page(\'edit-comments.php\' );
}
add_action(\'admin_menu\', \'remove_posts_menu\');
