Creativ Multiconcep Drupal Theme

I'm getting an error message after I upload the Creativ theme:

PDOException: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES) in lock_may_be_available() (line 167 of /home....../includes/lock.inc).

Hello customer,

The error means the account connect to mysql incorrect in settings.php file. Please open this file and change to correct account.

Thank you.

Oh...you mean the user name or password is wrong in settings.php?

Got it working!  Thanks!

I would like to reduce the height of dexp_menu in the navigation region.

How can I do it?

I am looking for Creativ Drupal theme for Druapl 8. Is Creativ theme for drupal 8 is available?
