[mcj]WordPress插件crayon-syntax-highlighter出现invalid range错误

今天在测试站点发现一个问题，网站头满屏的：

Warning: preg_replace(): Compilation failed: invalid range in character class at offset 4 in /www/wwwroot/www.machunjie.com/wp-content/plugins/crayon-syntax-highlighter/crayon_langs.class.php on line 340

Warning: preg_replace(): Compilation failed: invalid range in character class at offset 4 in /www/wwwroot/www.machunjie.com/wp-content/plugins/crayon-syntax-highlighter/crayon_langs.class.php on line 340

Warning: preg_replace(): Compilation failed: invalid range in character class at offset 4 in /www/wwwroot/www.machunjie.com/wp-content/plugins/crayon-syntax-highlighter/crayon_langs.class.php on line 340

有点奇怪，主站就没事，找到文件查看：

	// Override
	function clean_id($id) {
        $id = CrayonUtil::space_to_hyphen( strtolower(trim($id)) );

        return preg_replace('/[^\w-+#]/msi', '', $id);
	}

找到报错的这一行，将return preg_replace('/[^\w-+#]/msi', '', $id);改为return preg_replace('/\[^\w-+#]/msi', '', $id);
