Issue with plugin loading/execution order?

[nhoizey]

I don't know where this error comes from, I get the following message:

The trace shows it happens in /usr/local/lib/ruby/gems/2.2.0/gems/jekyll-tagging-1.0.1/lib/jekyll/tagging.rb:133:in 'tag_url'

I first opened this issue in the jekyll-archive project:
jekyll/jekyll-archives#49

There, @alfredxing told me this:

Although I'm not familiar with the jekyll-tagging plugin, it seems like that plugin is being initialized after jekyll-archives in this case, which means you can't use the tags filter in an archive page.

You might want to raise the issue with the developer of that plugin. I believe it's possible to access the site config in a Liquid filter (using Liquid context registers) without needing to initialize the generator first.

Any hints? Thanks in advance for your help.

Try playing with the priority flag.
