I did just that a while ago. Seeing on my server what you've been seeing in yours I've just turned it off for a day or so, and when I turned it on just to be sure that I have to scrap it and start again, it started working just fine. So, I'd say, let it be, let it rest, come back to it later. Or I dunno, maybe it was just a fluke.
I had the same situation, ended up just changing the subdomain and starting fresh
There might be something you can do but I'm not smart enough to find it
