Getting Talk Widget active academic theme

I’m having difficulty getting a widget working with the hugo academic theme.

the website is here: sjkiss.github.io and the files are here: http://github.io/sjkiss/sjkiss.github.io.

I have slides here https://sjkiss.github.io/files/presentations/18_04_04_syracuse.html#(1)

But I cannot for the life of me get a “talk” widget to work. I have a .md file for some information included in the “content/talk” folder, and I build the site. The config.toml file has a widget added in the main menu, as instructed, #talk. There is a menu button to that effect but it’s not active.

I hope I’ve provided enough information here.
