SQL Trouble While Scripting

[Barry]

Hello friends, I am trying to install a php script on my website, but I am having trouble entering the database information. I have created a database and a user from Cpanel. I have linked them together. Then I made the necessary changes in the database file of the script, but when I enter the information, I encounter the error "SQLSTATE[28000] [1045] Access denied for user 'admin'@'localhost' (using password: YES)" on the site. I would be very happy if a friend who can help me with a program like TW could help. THANK YOU
