I just found what looks like a bug in websitebaker.
When adding a page to the news with a title ending with '...', I got an error message when trying clicking the 'read more' link below the post.
Page title: 'In the beginning...'
The URL:
http://localhost/cms/pages/posts/in-the-beginning...2.phpI haven't looked at WB's sources yet, so I have no idea what's causing this.
