The change to old theme doesn't work

So this is how it looks when I changed to old theme. Am I doing something wrong?

just either wait or reload the website

I’ve reloaded it many times

have you tried saving the changes and closing and reopening the tab?

yes

then idk sorry

Yea it took the website a fat day for it to recognize changes to my preferences.

Also make sure you have the color color scheme to default when you have either theme equipped.
