What 'bunny123' was really asking (we were talking) is to disable the rule that involves throwing a 403 when someone specifies something like '5=3' through user input ($_GET, $_POST, $_COOKIE), which is there to prevent "second layer" SQL injections.
In addition, the user would like to remove any rules that would prevent URLs, tags (HTML, JS..), or just words that could end up appearing as SQL statements from being blocked.
