DATABASE CONNECTION FAILED
--------------------------
Reason: SQLSTATE[28000] [1045] Access denied for user 'q6l455m7n8ai_xxxx'@'localhost' (using password: YES)

Using these values from config.php:
  DB_HOST = localhost
  DB_NAME = q6l455m7n8ai_xxxx
  DB_USER = q6l455m7n8ai_xxxx
  DB_PASS = (set, 21 chars)

Common fixes:
  * 'Access denied'   -> wrong user/password, OR the user isn't
                         added to the database with All Privileges.
  * 'Unknown database'-> DB_NAME doesn't match (check the prefix).
  * Make sure both DB_NAME and DB_USER start with q6l455m7n8ai_
