> Whether the database was created using SQLyog?
No, it was created by Plesk.
> Do you find the database listed under the specific user it was created ?
SQLyog shows the database name without backslashes. It doesn’t show privileges for the user for that database.
> To view objects on which the user has privileges, check “Show only privileged objects” at the bottom left corner of the ‘User Manager’ dialog.
Oh, I have overlooked that feature completely before. Very useful!
> After checking the checkbox, do you find the object to which the user has privileges in the list?
Yes, SQLyog then shows the database name with backslashes.
