ACCESS DENIED FOR USER

[Datuned]

Hello, I am new to VestaCP. I created a database and user, then I was able to log in to PhPmyadmin. I got this error "Failed to connect to MySQL: Access denied for user 'admin_datuned'@'localhost' to database ' admin_store'" when I tried to enter data into my tables from my website.

Someone should please help me out.
