Hello to all, I have installed yesterday a server with Fedora 13 as operating server and ISPConfig 2. The problem is that i cannot use any PHP operating CMS. It gives me a lot of errors. If i use php fusion CMS i get errors and it dowsn't read the php code as it should (example - cnplesoianu.ro ). If i try to install joomls it gives me errors (wich i see in the error log) and shows a blank page. PHP Fatal error: Class 'JVersion' not found in /home/www/web1/web/libraries/cms.php on line 29 In cms.php i have // Define the Joomla version if not already defined. if (!defined('JVERSION')) { $jversion = new JVersion; define('JVERSION', $jversion->getShortVersion()); } Triyed with diferent versions of joomla, even with a back-up of an old site and same problem. I think it is a PHP problem but i cannot find it. Can anyone give some indications of how to resolve this problem?
