1. during the development on localhost, you extension works fine: no real problem
2. today, I transfer all my site in production. And I have none echo of Freichat on the users' screens.

My idea: any address of the right production Url must be changed now ???
Please: what are the parameters to be updated and in what file ?
=========================================

Here is the url of my site: http://www.planet-annonces.com
Best regards, admin.

ps a quarter after my post:
------------------------------------------
I have updated the parameters of the database in the "arg.php" file: now, I see the mini window of Freichat, but none icons, none members, ... on the screen !
Look at this part of my "arg.php" file (I have just hidden here the sensible parameters):
/* Data base details */
$con='mysql';
$username='********';
$password='********';
$client_db_name='*********';
$host='localhost';

Looks like there are double www. in your requests

Go here http://planet-annonces.com/en/

You will see that the chat works now .

You can do one thing ,

Go to ~/freichat/client/freichat.js

Then

In function analyse()

Add this line

freidefines.url = freidefines.url.replace(/www.www./g,"www.");

I have updated this file as you write it, but now: the mini window of Freichat is not on the screen !!!

ps: I have written this line in the first position, immediately after the title of the function analyse() (may be an error of me). I forgot to specify that it is a "french site" (cf. fr, and not "en")
Thanks admin for your help.

Yes you made a error in adding the code

The current code in your file is

FreiChat.analyse=function()


freidefines.url = freidefines.url.replace(/www.www./g,"www.");
{
    if(FreiChat.ses_status==4)
        {
         FreiChat.freichatopt("goOnline");
        }
.
.
.

FreiChat.analyse=function()
{
freidefines.url = freidefines.url.replace(/www.www./g,"www.");

    if(FreiChat.ses_status==4)
        {
         FreiChat.freichatopt("goOnline");
        }
.
.
.

Well found, admin: you solved my problem ... and during a Sunday !
Thank you very much.

ps: just a "last" problem: on the Freichat window, we don't see the right icons of the theme. Freichat doesn't find the right pictures, so it takes ghost icons with Chrome and the word "option" with Firefox ! On localhost, I have not a such problem: all is right !
My real url is: http://www.planet-annonces.com/fr

Best regards, admin

Add the same line ie

freidefines.url = freidefines.url.replace(/www.www./g,"www.");

That's right: marvellous support, admin.
And ... "merci beaucoup"!
