I get what appear to be two errors when trying to access SimGallery - see details below

Strict Standards: Declaration of SIMGalleryTableSGNotifications::save() should be compatible with JTable::save($src, $orderingFilter = '', $ignore = '') in /home/hetclub/public_html/hettest/components/com_simgallery/tables/sgnotifications.php on line 41

Fatal error: Call to undefined function ngettext() in /home/hetclub/public_html/hettest/components/com_simgallery/helpers/html.php on line 1595

Note that gettext is installed on the system
