Error on creating new page by admin panel

[Diazapam]

If you create a new page on admin panel and you try to put code inside it you get this error:
Also if you edit a page that has content it will become empty again <_<

Have you changed anything in security.php ?

No, nothing.

Yes I see, someone changed security.php on SVN.

Replace it with this one:

<?php 

function __sql_regcase($string){
        $max = strlen($string);
        $ret = '';
        for ($i = 0; $i < $max; $i++) {
                $char   = substr($string,$i,1);
                $up     = strtoupper($char);
                $low    = strtolower($char);
                $ret    .=($up != $low) ? '[' . $up . $low . ']' : $char;
        }
        
        return $ret;
} 
function escape($data) {
        $data = preg_replace(__sql_regcase("/(from|select|insert|delete|where|drop table|show tables|#|\*|--|\\\\)/"),"", $data);
        return $data;
}

foreach($_POST as $key=>$value) {
        $_POST[$key.'Original'] = $value;
        $_POST[$key] = escape($value);
}
if($config['engine']['enable_query_strings']) {
        foreach($_GET as $key=>$value) {
                $_GET[$key] = escape($value);
        }
        $_REQUEST = array_merge($_GET, $_POST);
} else {
        $_REQUEST = $_POST;
}


?>

Worked fine
