I recently had to do a complete reinstall of jupyter on my machine. Since then, when I use nbextensions to convert my notebooks to an html file, the table of contents links to the original notebook rather than the new html file. Before, the basic command jupyter nbconvert --to html mynotebook.ipynb produced a functional table of contents.
Unfortunately, I have no idea why toc2 is no longer properly converting to HTML. I will appreciate any insights that anyone can give me.
It turns out that it was a bug introduced to toc2 by a recent update. toc2 has since been updated to fix this issue.
