By mistake, I have created a duplicate database in the phpMyAdmin page of cPanel. I want to delete this database, but I am not able to find any delete button in the UI.
Taking a queue from michael's answer above, I was unable to find the DROP Database command on my phpMyAdmin console in the localhost.
Apparantly I was missing a setting. Go to config.inc.php file of the phpMyAdmin folder, and add this:
$cfg['AllowUserDropDatabase'] = true;
Save and restart the local server and the command appears inside the console.
