Okay, I finally found where that "return better old site " button was hiding.

Notes:

to find the old design site go to the site settings and click on a button that's all it is at the very bottom of the site settings

oh boy this sucks for people who want to have a site that works is not a joke for the very bottom of the site settings find the old design site a button that you have to click site that works. oh boy this sucks, what and why?
