I have an issue with the Live Server extension in VS code. I’m learning html & css and I installed the extension when I was working on a file website.html in a folder named Lesson 1. It worked well. The I went on the Lesson 4 folder and tried to open with live server a file named buttons.html, and I got this in chrome :this is what was opened.
What should I do?

I tried to copy the buttons.html file in the Lesson 1 folder and it worked well. Then I tried to change some settings in the extension but I didn’t know pretty much what I was doing and it was changing nothing so I got back to default settings. I closed and re-opened VS Code between each test and it didn’t help.
