Not loading the page it is supposed to load

Hello,

I have a github page that isn’t loading the page or code that it is supposed to load. The link to it is https://ll931217.github.io/startpage. The page seems to have code from https://ll931217.github.io/. This is what it is supposed to look like on my startpage: https://i.imgur.com/qLjA5Ah.png

Yes, I am aware of the console error about nprogress but there shouldn’t even be that code in my build.js file. The source file for my startpage is https://github.com/ll931217/startpage in the master branch, if you look through the source files, you shouldn’t be able to find nprogress anywhere except in https://github.com/ll931217/ll931217.github.io. What is the cause of my problem? Because when I cloned the startpage, gh-pages branch, to my machine, and used “http-server” with nodejs it works fine.
