I have used freichat in PHP.
I got the js generated from http://evnix-dot-com.appspot.com/?time=1325470593 via some web proxy and named tmp.js, then I modified test.php to

<script type="text/javascript" language="javascipt" src="tmp.js?time=&lt;?php%20echo%20time()%20?&gt;"></script>

INSTEAD OF

<script type="text/javascript" language="javascipt" src="http://evnix-dot-com.appspot.com/?time=&lt;?php%20echo%20time();%20?&gt;"></script>


to use the tmp.js instead the original url.

But it cause an error.
"$jn is not a function"

Can you please give me solution?

First thing to note is that you are not allowed to modify any external JS files. They are not included in the free license.
Why dont you use the link to evnix-dot-com.appspot.com??

I copied whole js from evnix-dot-com.appspot.com and paste it to tmp.js
and i used this tmp.js file instead of evnix-dot-com.appspot.com url.

But its not working.
Please give me solution for using js instead of evnix-dot-com.appspot.com URL.

Thank you.

And I am not using Char rooms. so is it possible to remove that link?

sorry but thats not possible in the current version(and hacking that external code is not legal as it is not part of the free license).
From the next major version, we will make registration as a requirement for download which means you will be able to load all your files locally.
