If you are getting the following error:
Error: 71400050 : Unable to perform action. Error: Access denied for user: ‘root@localhost’ (Using password: YES)
This errors occurs if the mySQL root user specified in Hosting Controller settings doesn’t has sufficient database privileges for the required operation.
SOLUTION
Grant all privileges to ‘root’ user and set this user in mySQL settings in Hosting Controller.
To grant privileges to root user, follow these steps:
Open command prompt. To open command prompt, click Start, click Run, and enter cmd.exe.
Go to /bin directory of mySQL (C:/mySQL/Bin).
Enter following command on command prompt:mysql -h 127.0.0.1 -u root -p
Set privileges for root user by entering following command on mySQL command line:mysql> grant all privileges on *.* to root@127.0.0.1 identified by ‘password’ with grant option;.
Note: ‘password’ is the password of root user and it must be given in the quotes.
