If your webserver runs on a non-standard port (i.e. your URL looks like this :
http://www.mysite.com:1234/), you'll need to do some tweaking to make it work.

1) apply the "quick fix" for login problems - see previous page :-)

That will already fix one of the problems...

2) in the file /includes/pnAPI.php, there is a function pnGetBaseURL that
returns the base URL of your site. You'll need to adapt it as follows :

Replace
    return "$proto$server$path/";
with
    // specify your own portnumber here
    $port = 1234;
    return "$proto$server:$port$path/";
