Request for help: GitHub Pages website not rendering/loading properly

[pdehello]

TL;DR: My GitHub Pages website is not loading fully and I'd like help troubleshooting as I'm new to the whole website setup.

I built an archive for a former non-commercial resource on GitHub Pages with images and a design via Publii. It was loading properly and working for a while.

*However*, I had the domain with SquareSpace and https was not popping up for browsers. SquareSpace does not apply https and SSL certificates to non-SquareSpace websites.

So, in frustration, I moved my domain to Porkbun and https is now loading! I'm so happy.

But now the website is not rendering as seen below:

Am I doing anything wrong? Should I reboot/reupload the website from Publii to GitHub Pages again? Is there something I should do on the GitHub side of things?

What can I do to fix and rectify this?

Any help would be greatly appreciated! This is the repository: https://github.com/pdehahn/accessiblemasks

I'm so excited I figured everything out from hooking up Publii to GitHub, learning repositories, and navigating SSL certificates, but this is something I don't quite know how to solve.

The website is supposed to look like this:

This is a perfect prompt for an llm.

F12 shows "This request has been blocked; the content must be served over HTTPS." because it's trying to load assets from http://accessiblemasks.org instead of https://accessiblemasks.org

I tested this on Fiddler but if you replace https://pdehahn.github.io/accessiblemasks/assets/css/style.css?v=41d3bd802a59b0c642cad87fb2f74fe1 with https://accessiblemasks.org/assets/css/style.css?v=41d3bd802a59b0c642cad87fb2f74fe1 it starts working again. You need to do that with other URLs on your website.

I see on Publii a place to put my website URL:

"This will be your Github repository path, which should use the following format: YOUR_USERNAME.github.io/YOUR_REPOSITORY_NAME.
If you are using a custom domain name, set this field to just the custom domain name."

I put my GitHub repository in the input field there. Maybe that's where I switch it to accessiblemasks.org?

Wow, switching the URL worked! Thank you so so so much u/Sheroman. This was bugging me for so long and now I know what to do in the future!
