Hi. I'm sorry for my English.
I'm using gladius 0.8.0 (edited by me).
In line 169 of gladius_create.php there is an error.
$this->offset = $unique_raw+strlen($unique_raw);
But print_r($unique_raw) return Array (  => KEY comment_approved (comment_approved)  => comment_approved ) because the preg_match function hasn't got PREG_OFFSET_CAPTURE.
