Upgrading to v6

Version: 6.2.1

Nikola tries fairly hard to be compatible between versions. However, there were a few areas which were getting clunky, and needed fxing. So, here's what you may need to change in your site.

If you need to change anything else, or something breaks, please write at nikola-discuss and I'll add further tweaks here.


The install_theme command is not working yet, get themes from https://github.com/getnikola/nikola-themes
There is no equivalent for the jinja-default theme yet. If you have a custom, jinja-based theme, upgrading is probably a bad idea right now.

Themes have been renamed:

  • site => bootstrap
  • orphan => base

Theme added:

  • base-jinja

Themes have been moved out of nikola and into nikola-themes:

  • default => oldfashioned at nikola-themes
  • jinja-default => not there yet, coming soon
  • monospace => monospace at nikola-themes
  • site-reveal => reveal at nikola-themes

You may have to change your THEME setting, or change the parent if you are using a custom theme. Also, some templates have been tweaked, but nothing should break for you.

Facebook comments support changed the HTML tag to:


If you want a custom theme to support comment systems other than disqus, you will need to:

  1. Replace mentions of disqus_helper.tmpl with comments_helper.tmpl
  2. Replace mentions of html_disqus with comment_form
  3. Replace mentions of html_disqus_link with comment_link
  4. Replace mentions of html_disqus_script with comment_link_script

If you don't, your theme should work just fine, but support only disqus comments.


A number of options have been renamed. In all cases, the behaviour should be exactly as before. If it's not, let me know. Also, you will get warnings. That doesn't mean things broke. They are there to inform you of what's happening, and that you need to tweak your config.

All the deprecated options will work during the v6 cycle, and only be removed in v7, when those warnings will become errors.
