Looks like the NextGEN Gallery 2.0.0 update released today breaks with NGP. All of my posts that use NGP (1.6.4) fail to load anything more than the header, post title and post-info -- no sidebar, no footer, no post, etc. (http://architourist.ca)
When I edit the post to remove the NGP statement, or for a post with only a NextGen shortcode, everything is OK. (NGG broke some CSS, but I think that's my fault :) )
Hopefully there is a simple solution for this.
