Thanks again for your help. I was able to get this resolved through my hosting company. (Thank goodness!)
OK! Thank you so much. I have one more question. The instructions on the search and replace script say to install root folder of my wordpress install, but I can’t access my wordpress account without getting that 404 error. And i’m not sure where the root folder would be even if I could access it.
Any ideas?
Thanks so much. I did look at that but am such a novice that I can’t quite understand whether what I’ve done is irreversible or if I can do the search and replace thing and get it back to normal.
