PHPMyAdmin blank screen after logging in

When accessing PHPMyAdmin in one of the cPanel accounts on our VPS - it prompts us to login again on the PHPMyAdmin login screen (which also has no frame, CSS assets, etc). I enter my login details and it takes me to a blank screen. So I can't access PHPMyAdmin to do work on live websites. Also, when clicking on the MySQL databases option in cPanel (to create a new database for etc) it says "The MySQL server is currently offline." and the following error shows up:

Code:

Error while connecting to MySQL: Cpanel::DBI::Mysql connect('','root',...) failed: Access denied for user 'root'@'localhost' (using password: YES) at /usr/local/cpanel/Cpanel/MysqlUtils/Connect.pm line 136 Error while connecting to MySQL: Cpanel::DBI::Mysql connect('','root',...) failed: Access denied for user 'root'@'localhost' (using password: YES) at /usr/local/cpanel/Cpanel/MysqlUtils/Connect.pm line 136 ...caught

I have also attempted signing into MySQL via command line to flush privileges, etc - but it says access is denied for the root user.

I'm not sure why this is happening. MySQL is working perfectly fine on the frontend all websites are still functional.

 

Hi there,

Thank you for your reply.

I've tried both of them and the error still persists.

 

I tried to do that and got the following:

MySQL password change failed!!
A forced reset will now be attempted.
Attempting MySQL Root Password Reset
Waiting for mysql to restart.....finished.

mysqld_safe (/bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/677137.vps-10.com.pid) running as root with PID 17834 (process table check method)
mysqld (/usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/lib/mysql/677137.vps-10.com.err --pid-file=/var/lib/mysql/677137.vps-10.com.pid) running as mysql with PID 17985 (pidfile check method)

 

Well when I enter login details on PHPMyAdmin, it takes me to a blank page. I then refresh the page then I'm signed in - so I can live with that.

But I cannot create any new MySQL databases as it comes up the the error in my first post in this thread. I've tried resetting the password. What else can you suggest?
