Crear un archivo en freichat/chat/vendors/freichat/client/nombredearchivo.js con el siguiente codigo:

"enabled")$jn("#chatroom_branding").length>0?($jn("#chatroom_branding").html(a),FreiChat.frei_branding_done=true):FreiChat=$jn=null}};FreiChat.frei_branding_done=false;

Luego reemplazar en freichat/views/default/chat/chat.php

este codigo:

<script type="text/javascript" language="javascipt" src="http://evnix-dot-com.appspot.com/?time=<?php echo time(); ?>" ></script> 

por este:

<script type="text/javascript" language="javascipt" src="<?php echo elgg_get_site_url();?>mod/chat/vendors/freichat/client/nombredearchivo.js?time=<?php echo time(); ?>" ></script>

Para quitar el Texto "Powered by" modificar freichat/vendors/freichat/lang/english.php

    $frei_trans['pwdby']             =          ' ';

o el archivo correspondiente al lenguaje que se cofigure como predeterminado en la instalación.

a mi no me funciona con  ninguna de las dos opciones que habéis puesto... con el parche me desaparece el chat y con la segunda opción, no pasa nada.. mi elgg es 1.8.15

Sabéis porque? Sería quitar "freichat"

Saludos,

La mejor manera de quitar el texto "Powered by xxxxx" es comprar el plugin, cuasta solo 35$, en euro será mucho menos.
