Arrowchat

[DesperadoN]

Anyone knows how to insert arrowchat php code ?
for example it says that i have to insert

<link type="text/css" rel="stylesheet" id="arrowchat_css" media="all" href="/forum/arrowchat/external.php?type=css" charset="utf-8" />
<script type="text/javascript" src="/forum/arrowchat/includes/js/jquery.js"></script>
<script type="text/javascript" src="/forum/arrowchat/includes/js/jquery-ui.js"></script>

into header

and this

<script type="text/javascript" src="/forum/arrowchat/external.php?type=djs" charset="utf-8"></script>
<script type="text/javascript" src="/forum/arrowchat/external.php?type=js" charset="utf-8"></script>

into footer

but when i do that i get:

An appropriate representation of the requested resource /forum/admincp/template.php could not be found on this server.

Additionally, a 406 Not Acceptable error was encountered while trying to use an ErrorDocument to handle the request.
