Is the quickstart package usable to start with a new site ? if yes, I'm experiencing some issues, the main issue is that, when I try to access to the backed I have the following message
View class not found [class, file]: cpanelViewcpanel, /htdocs/public/www/administrator/components/com_cpanel/views/cpanel/view.html.php
the cpanel component is supposed not to be installed, how to fix this ?

thanks

Did you follow the instructions as posted here ? nuevvo.com/documentation/general-resources/installation/item/31-how-to-install-the-quickstart-package

Also which version of the quickstart did you use? Finally did you update Joomla! or install any other extension?

the version is the j3x 20131129 and I've followed the instructions. no extensions nether joomla update installed.
another strange issue is when I try to access to extension manager, I've no errors nether fields (only menus are shown)

Chances are: Your server does not support Joomla! 3.x (possible but a longshot).

or the downloaded file was corrupted. You can try redownloading the quickstart package. You can also try repairing the db tables and fixind your file/ folder permissions before reinstalling. One extension which does these thing is Admin Tools. extensions.joomla.org/extensions/access-a-security/site-security/site-protection/14087
