Thanks for all Riklaunim,
It doenst work. Can i use your e-mail of gmail to use gtalk to solve the problem?
OK ALL WORKS FINE, here are my settings if anyone have same problems:
I use domain.com and forum.domain.com
config.php only change this
$cookie_domain = 'domain.com';
$cookie_path = '/';
and at jl-punn.php i only change two things:
define('PUNPATH', '../forum.domain.com/'); // path to punbb folder
define('PUNPREFIX', 'pun_'); // punBB table prefix, -----> Yo can use another prefix or use blank if none.
THANKS FOR ALL RIKLAUNIM ;-)
