lot of javascript issues on a fresh installation : unable to use piwik (no replies)

Hi

i installed last piwik server on last easyphp 14.11 with APACHE 2.4.7 MYSQL 5.6.15 PHP 5.5.8. on a Intel i-5 4GB ram notebook.

empty server, only piwik installed.

piwik runs very slow , but this is not the main problem.

the main problem is the huge amounth of javascript issues that i can see in chrome console, for example, in the login page :

Uncaught SyntaxError: Unexpected token > index.php:20
Uncaught ReferenceError: jQuery is not defined jquery.placeholder.js?cb=3e56eeca24d975c41d932d6ce7d79924:157
Uncaught TypeError: Cannot set property 'smartbanner' of undefined jquery.smartbanner.js?cb=3e56eeca24d975c41d932d6ce7d79924:166
Uncaught ReferenceError: $ is not defined (index):33
Uncaught ReferenceError: $ is not defined (index):45

it looks like jQuery was not loaded, but this resource are sent by localhost, so there can be a server issue?

what about those problems in a fresh installation?

thanks

Andrea
