Access the admin panel temporarily through this.

yes i add some ads in the widget box in my sidebars.
Well thanks for the link to access admin panel. But when my admin panel will show in my forum? Did i have to remove ads from my widgets?

Yes you have to remove that widget or rather delete it. Because, that code is making the admin panel link disappear.
