Phpmyadmin php myadmin是一个空白的白色屏幕

据我所知，Mysql工作正常，我只是无法通过phpmyadmin访问它，它报告了500个错误

我不知道这是因为CA证书CA.pem是自签名的还是[InnoDB]InnoDB初始化已经结束，或者完全是其他原因

我确实更改了一些内存日志，并在/etc/mysql/mysql.conf.d/mysqld.cnf中将performance_schema设置为0，以释放内存，因为内存很低，但后来我又重新更改了它，现在我的内存并不低

这可能与重定向到https有关吗

这个问题直到最近才出现

我需要尽快访问它。我完全迷路了，请让我知道任何见解

谢谢大家!

我不知道是什么问题，我卸载并重新安装了phpmyadmin，现在一切正常。
