It’s resolved for me. I don’t know what the problem is but the only advice I can give you is to wait it out because it came back for me, and I didn’t have to re-upload anything which made me very happy.
Funny how GoDaddy says it’s not their problem (even though I installed WordPress on my site THROUGH GoDaddy), and apparently it’s not a WordPress problem either. What could have caused this to happen?
