Problems creating/deleting... albums in Gallery embedded in postnuke

Hi!!

I have installed Apache 2.0.55, Postnuke .762, Gallery 1.5.3 and PHP 5.1.2.

I have embedded Gallery into Postnuke which works just fine. However when I´m going to create albums I just get a blank popup, and nothing happens? It's the same when I'm trying to delete an album created when Gallery was run standalone.

This is the link executed when trying to create the album

http://192.168.0.104/index.php?return=http%3A%2F%2F192.168.0.104%2Findex.php%3Fname%3DGallery%26include%3Dview_album.php&cmd=new-album&name=Gallery&include=do_command.php

I've also checked the Apache errorlog, but I cannot interpret the error messages?

I run my solution on Windows XP.

Does anybody have a clue to this?
