Hi Quincy,
Whenever you see "deprecated", it basically means the function no longer works for that version. My guess is that previously you were on PHP 5.2 and then once you updated (or your host updated) your server to PHP 5.3, the error appeared.
Check out the following API documentation:
php.net/manual/en/function.ereg-replace.php My guess is that using the latest version of RokBox (make sure you make a backup before updating), would fix the issue as they've likely updated the extension for PHP 5.3 by now.
Hope this helps!
Kind regards,
Nick
