Hi,

I have upgraded 2.6 to 2.7 and all is correct except when I visit some pages (like signup page) I get this error:

Fatal error: Zend_Json::require_once() [function.require]: Failed opening required 'Zend/Json/Encoder.php' (include_path='.:/var/www/vhosts/domainname/httpdocs/include/:/var/www/vhosts/nereliatube.com/httpdocs/include/PEAR/:.:') in /var/www/vhosts/domainname/httpdocs/include/Zend/Json.php on line 98


Can you help me?
