Same problem here !

[urspx]

Have this problem also!

[manunamz]

I think the problem is that I am currently using both jekyll-wikilinks and jekyll-namespaces with my graph...So this might be fixed by simply adding jekyll-namespaces to your Gemfile.

But that shouldn't happen. I will be sure to fix this.

[manunamz]

Actually, try setting this in the configs if you haven't already:

graph:
  tree:
    enabled: false

[xplosionmind]

try setting this

That’s it. Thank you very much!
