Nach dem kopieren von Joomla zu einer lokalen XAMPP Installation 1.8.1 tauchen folgende Fehler auf und Joomla startet nicht:

Strict Standards: Non-static method JLoader::import() should not be called statically in ~\joomla\import.php on line 29

Warning: Cannot modify header information - headers already sent by (output started at ~\libraries\loader.php:138) in ~\libraries\joomla\factory.php on line 566

Eine Lösung für das Problem ist in der php.ini die folgenden Einstellungen zu ändern:

error_reporting = E_ALL | E_STRICT

zu

error_reporting = E_ALL & ~E_STRICT

und

display_errors = On

zu

display_errors = Off

Ab und an reicht es auch zu wenn man in der configuration.php im Joomla Root Ordner folgende Zeilen ändert:

var $error_reporting = '-1′;

zu

var $error_reporting = '6135′;
