PHPBB 3 for v1.3.8

[Loter]

Hello,

I'm using ZC 1.3.9h and phpbb 3.0.8 latest stable release.
The phpbb integration is not working on my zc installation.
I have
define('DIR_WS_PHPBB', '/forum/');
defined in /includes/configure.php
and enabled phpbb linkage from control panel.

when user on zc registers, nothing happens on phpbb3. What is the trick? I have tried to use class.phpbb.php posted on first page of this thread, but no luck. Please help me to find the solution.

Thank you

Problem solved by changing DIR_WS_PHPBB to
define('DIR_WS_PHPBB', '/var/www/vhosts/..../httpdocs/forum');
