Thunk

I discovered a small programming mistake this morning involving a misnamed variable (because PHP doesn’t detect nonexistent variables until it actually encounters it). I fixed it and the updated one is already uploaded here. I also added a note after installation reminding the user to add the footnotes classes to the stylesheets.

Update #2

I discovered another stupid typo which causes the syntax matching to fail. Also, I fixed a bug where the note parameter gets duplicated everytime a post with footnotes gets edited. The updated one is already posted. Please use this update immediately instead of the previous one.
