Thread:Help talk:Installation/Upgrading from 1.8.x without Shell Access

Since Validator is somehow integrated in SMW 1.9.x ("$IP/extensions/SemanticMediawiki/extensions/Validator/") isn't it recommended or even required to remove the Validator line ("require_once "$IP/extensions/Validator/Validator.php";") that should exist in LS.php from the previous SMW 1.8 installation?
