After upgrading to 2.0 I'm experiencing many URL errors leading to Page not found issues.
Galleries display find and I can drill down to nested galleries without an issue but albums can not be displayed.
Example: http://www.epoch-larp.ca/galleries/photos/2012-photo-gallery/ is the gallery but when I click on an album it goes to http://www.epoch-larp.ca/galleries/photos/2012-photo-gallery/wordpress/nggallery/2012/march-2012
Imagebrowsing pages show the first image correctly but then fail to display subsequent images.
Example: http://www.epoch-larp.ca/galleries/artwork/artwork-2012/ becomes http://www.epoch-larp.ca/galleries/artwork/artwork-2012/wordpress/nggallery/image/elven-maid-and-kaern-gentlemen when I press the next button.
I did turn off all other plugins to see if that helped but it did not. I also tried updating the short codes but that also did not seem to effect the issue.
