If you want me to comment about your site I would need to be able to see your site. It is hard enough it is not in english but its also locked down. PhotoPost vBGallery
The link works and is translated fine by the script from what I see that is a fresh vbgallery 3.01
I would suggest you check your htaccess on the site any kind of redirects because its your forum or some addon causing your issue. maybe vbseo
cant say as I do not know what is setup on your site.
