Hello everybody, I have an issue which I was trying to solve for last few days. Here is my simple website repo: https://github.com/Jurek33/Robo_Friends . Here is the whole story: 

1. I created a website locally using create react app. 

2. I put it into my new github repo and followed the documentation to publish it using github pages.

3. It used to work fine before I decided to make some changes in a few files and push them to the repo.

4. After that I have noticed that changes do not apply on github pages and I still see the same website as before.

5. I figured out that I have 2 branches (master and gh-pages). Then I realized that I have beed applying all the changes to master branch but my website was publishing from gh-pages branch source. So I switch the source to master branch and deleted gh-pages branch

6. Since then it does not uplad an html file and I only see an empty page. Here are an errors I see on a console

   Here are the soultions I already tried but they did not work for me:

7. Choosing a Jekyll theme (on some forums people say that it could be a problem even if the website does not use Jekyll)

8. Putting an html file into main folder

9. Changing github pages source (no matter what source I choose it is still not working)

10. Changing an html file path 

11. Deleting an old repository and putting all local files into a new repository

12. Cleaning chrome browser cache

If someone knows what am I doing wrong and why I get this errors please let me know what is it. I will appreciate any help.
