Problems with ?> at the end of included files

[decola]

Hi everybody!
I've just tried PFC...simply marvellous! Congratulations to developers!

I've integrated PFC in my web portal.
At the top pf index.php, before including phpfreechat.class.php, I've included some php-file with class definitions useful for the integration.
A strange issue arise. If the included files end with ?>, PFC doesn't work!

Anybody can find out the problem?

Thanx

Could you post the error message ?

But, I think this is because you have a line break or a space or a special charactere after your "?>"

[decola]

Is a line break or a space after "?>" so important?
I'll test it.

No error messages. The page loads but you can't see the user column and the messages column: a big white zone instead of them. And you can't write your message.

Yes because with a white space before session startion will throw an error.

You're right! A space after ?> is really important because a space begins the output of the webpage.
So the warning is about session:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /var/www/XXXXXXXXXXXXX/class_test.php:24)

The chat is "loaded" but you can't see the user column and the message column.


Then I've tried to add ob_start() at the start of the script and ob_end_flush() at the end of it. The warning message is not shown again but you can't see the user column and the message column, anyway.
