[Alain91]

On PHP 5.2 an error occurs when calling Admin->preferences->general settings (url =
http://localhost/xoops/htdocs/modules/system/admin.php?fct=preferences&op=show&confcat_id=1)

Fatal error: Declaration of XoopsForm::getElements() must be compatible with that of XoopsFormContainer::getElements() in xxx\www\xoops\htdocs\class\xoopsform\form.php on line 27
