Hello,
Thank you for your help. However, I didn't touch anything; I didn't touch the files including (configuration.php), I didn't touch the database, so how can this happen?It must be hacking... in case it is a hacking, then how can I prevent my site?

The best bet is to secure your site as per the instructions at Joomla.org.
Best of luck.
