 #### My site doesn't work when I enable `related_blog_posts`. Why?
 
-This is probably due to the [classifier reborn](https://github.com/jekyll/classifier-reborn) plugin, which is used to calculate related posts. If the error states `Liquid Exception: Zero vectors can not be normalized...`, it means that it could not calculate related posts for a specific post. This is usually caused by [empty or minimal blog posts](https://github.com/jekyll/classifier-reborn/issues/64) without meaningful words (i.e. only [stop words](https://en.wikipedia.org/wiki/Stop_words)) or even [specific characters](https://github.com/jekyll/classifier-reborn/issues/194) you used in your posts. Also, the calculus for similar posts are made for every `post`, which means every page that uses `layout: post`, including the announcements. To change this behavior, simply add `related_posts: false` to the front matter of the page you don't want to display related posts on.

Another solution is to disable the lsi (latent semantic indexing) entirely by removing the `--lsi` flag in the code. Related issue: [#1828](https://github.com/alshedivat/al-folio/issues/1828).
