I can't access the Templates and Themes pages in the Admin section when I click the Quick Access links I stay on the Dashboard page.
Is there any other way to access the Templates page?

Just before it happened I typed in a wrong page address in the addess bar (i.e. - http://www.############/forumdisplay.php?fid=67 - the page doesn't exist) and got an error message saying "Invalid Forum".

Post AdminCP logins in private Inquiries forum so someone among staff could take a peak look on this.

Thanks - IT's not a live site so I wiped the server and started again.
