Why is the title not updated

[luxuryrisen]

I have modified the title and description for two days, but the code on the home page has not changed, and the old one is still displayed

Did you click Save button after changing? Also try to clear your browser cache and check again?

Of course it was saved, and I used a second computer to access it without any cache
