I created a forder phpgrid at domain/phpgrid and uploaded all files and folders into this. Then I added host, dbname, user and password to config file( renamed config.sample to config) and uploaded the config. Now When I am trying to open domain/phpgrid/index.php it shows error with message -: Access denied for user 'mroot'@'localhost' (using password: NO) – SELECT * FROM clients WHERE 1=1 LIMIT 1 OFFSET 0. while I am not using mroot user for database I am using another username and password mroot is my user for cpanel. Please help to understand if I am doing something wrong.
