Sorry I didn't update the code here.  I'll add the TODO list here in a few hours if possible, or some days.  Right now I'm installing the Live Chat on a live environment, let's see what happens.

P. D. :

Installation went fine, chat didn't work at first, then patched the files and everything seems to be fine.  Files modified (edited from original):

/class/aardvark. php

line 77:
setcookie('aardvark_'. $this->variables_send[$key ]['variable' ], $this->variables_send[$key ]['data' ], $time, '/', $domain);

to (sending the cookie and the custom header):
setcookie('aardvark_'. $this->variables_send[$key ]['variable' ], $this->variables_send[$key ]['data' ], $time, '/', $domain);
header("Custom-header: aardvark_". $this->variables_send[$key ]['variable' ]. "=". rawurlencode($this->variables_send[$key ]['data' ]),false);

/class/js/aardvark. php

line 52 (reads the cookie header, removing date and path info):
} else { headers = eval(object+". xmlhttp. getResponseHeader('Set-Cookie')"); headers = headers. split("path=/"); for (i = 0; i < headers. length; i++) { headers[i ] = headers[i ]. split("; "); if (headers[i ][0 ] !== '') { if (headers[i ][0 ]. substring(0, 2) == ', ') { content += headers[i ][0 ]. substring(2, headers[i ][0 ]. length) + '; ';} else if (headers[i ][0 ]. substring(0, 1) == "\n") { content += headers[i ][0 ]. substring(1, headers[i ][0 ]. length) + '; ';} else { content += headers[i ][0 ] + '; ';}
}
}
}

to (returns bare custom header):
} else { headers = eval(object+". xmlhttp. getResponseHeader('Custom-header')"); content = (headers) ? headers : "";
}

Tried to attach the files I originally edited at my computer, but didn't have enough permissions.

Just tested with FireFox 2. 0. 2, Mac OS X 10. 3: 1 error, message from FireBug
document. getElementById("aardvark_div_" + object) has no properties
}; this. xmlhttp. open("GET", this. url, tr. . . new Image(); this. image. src = this. url;}

Hello,

happy to be here, I'm French and it will not be easy ;-)
Obviously for me too in Firefox, the cat is in charge but it gets stuck at this stage of loading.   It works fine in IE. 
Being not very good at English I did not understand the explanation given here. 

Maybe someone could send me nice e mail changed pages ;-)

A priori, a French translation of the script exists, but the link is dead, maybe someone who has this file english. txt may wish to contact me, thank you

Thank you in advance for your help. 
Translation Google ;-)
Good day

Yes I am willing changed files
