strange problem when saving a page

[adrnlnrsh]

This worked perfectly. Thank you.

I think there is an extra ')' in the second if. Should read.

Code:

// check form referrer - needs siteurl and edit.php in it.
if (isset($_SERVER['HTTP_REFERER'])) {
        if ( !(strpos(str_replace('http://www.', '', $SITEURL), $_SERVER['HTTP_REFERER']) === false) || !(strpos("edit.php", $_SERVER['HTTP_REFERER']) === false)) {
                echo "<b>Invalid Referer</b><br />-------<br />";
                echo 'Invalid Referer: ' . $_SERVER['HTTP_REFERER'];
                die;
        }
}
