I've been trying to create a child theme and having trouble doing so on GoDaddy's ftp manager. So, I decided to try it on FileZilla which I've been working with for 4 or 5 years. As I was downloading my info into FileZilla I saw an old "Page under construction" index file I had up before I came with WordPress. I tried to delete it. I deleted the wrong index! Now all I can bring up is the old "Page under construction" index file page. Is there anything I can do to fix this? Or will I have to start from scratch and reinstall WordPress? Or what?
