In advance, thanks for the help. I have been trying to sort this out on my own for days now.
I allowed a domain name registration to lapse and was able to re-register it with Dreamhost (where it was registered by me in the first place) and now the site won't show. I am getting a "Problem Loading Page/Can't find the server" error.
When I first selected the hosting for the registered domain I was in the incorrect user, but after my initial problems getting the site to show decided to start over from scratch and changed the user to my regular user, which created a new directory in my FTP, to which I uploaded all the files again from my local backup.
The domain is "fully hosted" by the same user that I am using to FTP the site (I use a freeware program called CoreFTP.) The permissions on all the directories and files seem correct. I can not figure out what I'm doing wrong here.
I've been a happy Dreamhost customer since 2006 and have had very few problems- this problem and seeing the threads in this forum are making me a bit nervous, though.
