I was building my site in a temporary folder and then moved it to the root folder. I did at first get the white screen on the home page, but then I managed to get that back by manually changing the site URLs. I was still unable to view the Admin screen. I could login, but was getting a white screen.
So, in my panic, I moved the site back to the original folder and am now getting a white screen all the time. I have again changed the URLs back to the original, deactivated the plugins, even deactivated the active theme. None of that helped. Any thoughts??
The original (and current URL):
The intended URL:
