Xampp Apache:检测到状态更改：已停止按Logs按钮查看错误日志并检查

我在xammp服务器中收到此错误消息，MySql将自动停止

我会尽力的

16:30:00  [Apache]  Status change detected: stopped
16:30:00  [Apache]  Error: Apache shutdown unexpectedly.

我也改变了这一点：

<VirtualHost _default_:443>

ServerName www.example.com:443

换成

Listen 8080
ServerName localhost:8080

请帮助我解决此问题：

更改端口号在更改前和更改后，我都会重新启动计算机，但会出现相同的错误

Listen 80 
ServerName localhost:80

Listen 8080
ServerName localhost:8080
