Error - no attribute 'homepage'

I'm trying to setup the plugin and I get the following error in the console log. ERROR - Error building page 'docs/WIP/index.md': 'ChartsPlugin' object has no attribute 'homepage'

The MkDocs server does not throw an error when I start the server with the following config.

mkdocs.yml

However, when I create a new document in a sub-directory, it throws an error.

Closing this issue. I tried a few changes to the mkdocs.yml file and it now appears to be working perfectly. The diffs are also identical. Sorry to bother you.

BTW - This is FANTASTIC and exactly what I was looking for.

Happy to see the issue solved itself :)
