No Insert Grid Button

* It seems that mssql and oracle drivers were already installed on your Joomla.
          New drivers were copied to /var/www/html/bidev2.com/libraries/joomla/database/database/ and old ones were renamed with postfix '_old'.
          If no other application on your Joomla page connects to Oracle or MS-SQL database, than you can safely ignore this message.
