Hello Jonayed, thank you so much of your quick answer!
You are right, I entered the wocommerce/ folder and noticed that many files are missing. I did what you said and reinstall wocommerce. But after I saw that my theme was totally mess, do I need to save theme before reinstalling wocommerce? Do I need to save database?
I have created the stage site myself in order to try things to resolve.
In original site https://www.georgianarts.com/ in dashboard is impossible to see Wocommerce part.
