I just upgraded to VB3.61 and PP5.31. Whenever you try to go to a gallery page, and it seems to be any gallery page, from an external domain or subdomain you get a blank page. Hitting refresh does nothing. If you click in the address bar and hit enter, sometimes it loads. If you then hit refresh after that it will usually load. What in the world could be causing this? Once you get the page to load you can surf the gallery without a problem. The same behavior exists in both IE and FF.
EDIT: Changing the setting for spider-friendly URLS has no effect.
