Connection to the database server has failed because the supplied account does not possess administrative privileges: Access denied for user

Hello,

Error code :

Error: Connection to the database server has failed because the supplied account does not possess administrative privileges:
Access denied for user ‘admin’@’localhost’ to database

 

This error means that MySQL administrator account that is used in Plesk does not have enough privileges to manage database/users in the MySQL server.

Solution :

root@server01[~]#mysql 
mysql>use mysql
mysql>select * from user where user='admin' \G
