@ RJGonzalez: www . kafekopteio . gr @ MikeChoy: I didn't install anything in my computer. I followed the instructions of this tutorial: http://www.siteground.com/tutorials/prestashop/prestashop_installation.htm (I found this tutorial by google-ing for "prestashop installation tutorials") Log on to the Front Office, address as shown in the the browser bar: http://kafekopteio.gr/authentication.php?back=my-account.php This is the error I receive when I try to log on to the admin panel: "There is 1 error - employee does not exist, or bad password" I also checked the config/settings.inc.php , I don't see any problem there.
