我是在 ubuntu 安裝 phpmyadmin 跟 mariadb
剛剛用到一半突然登不進去？

phpmyadmin/index.php?token=38c2c8ddaee6d0bcf68dd2edac0b039b
雖然他有顯示 token
但是他就回到原本的登入頁面上，一直都進不去。。。。。
這是怎樣的問題啊？？？apache 都還是正常。。。
資料庫的東西還是都撈的到。。。。。沒異常
怎麼會這樣？

PS 輸入錯誤密碼還會報錯： #1045 - Access denied for user 'root'@'localhost' (using password: YES)

就是登不進？？？？

最後的錯誤是
