change path problem of X7 chat 2.0.5

[Dorbomil]

Hello everybody,

Not so long ago I have downloaded X7 chat.
Seams to be suitable for service what I am doing.
And I looks quiet nice.

In basic:
First. I have 'www.my_domain.com/system/shoutbox/index.php' (+other files of X7 chat)
If I rune it as a 'www.my_domain.com/system/shoutbox/' , then work perfectly with this adress
Now I have also 'www.my_domain.com/index.php' . It give me of course access to whole page.
Now If I select any sub page, I have always 'www.my_domain.com/index.ph?site=some-page

Thing is, I would like to do the same with a X7 chat.
If i select  'www.my_domain.com/index.ph?site=shoutbox' so I mean shoutbox should appear, Then I suppose to have my chat.
Is really important to me to do not show full path of folders but only index.php and after sign '?', If you know what I mean.

I know I can change code with path in each file of X7 chat. But that a lot of work. And I ask if is any way to avoid that.
Also I need change all buttons to form with GET or POST method. But I think I can do this manually.

My question is, It is possible to this thing with minimize of work?
If this kind of topic already exits then I do apologize, but I have not found it.

Kind regards,
Dobromil
