igor and all I found Igor's prior RSS feed from my backup and it works now. it was in the file inc>design.inc.php line 1296

<?= htmlspecialchars_adv( $oItem -> description ) ?>

replaced it with your prior fix of

<?= //htmlspecialchars_adv( $oItem -> description ) ?>
<?= ( $oItem -> description ) ?>

and now my RSS formats properly.

Good luck all...

I still have problem with Admin screen showing error lines when i go into the forum screen.
