我是.NET开发人员，正在尝试开发一些PHP应用程序。
我在Windows上安装了XAMPP没有问题，然后正确地启动了Apache和MySQL。
之后，为了更新我的PHPMyAdmin版本，我遵循了以下文章：
https://www.ostraining.com/blog/coding/update-phpmyadmin/
但之后我的MySQL服务不再启动了。如果我打开日志，我会阅读以下行：
2016-12-21 23:22:26 21c4 InnoDB: Warning: Using innodb_additional_mem_pool_size is DEPRECATED. This option may be removed in future releases, together with the option innodb_use_sys_malloc and with the InnoDB's internal memory allocator.

有人有同样的问题吗？
提前致谢
修改
有人指出，我的错误与Making MySQL work with utf-8 in my.cnf configuration file
相同然而，这种情况的解决方案对我不起作用。
我尝试执行mysql_upgrade但该命令显然无效，因为mysql服务已停止。
修改
我从头开始重新安装XAMPP，和以前一样，它正确启动。但是，在几次重启后，它不再启动（总是出现相同的错误）。
