First, since you're running Lion the user library is invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
Now you need to find a file named Domain.sites on your external hard drrive among the files you backed up. To do so dowload and use Find Any File to search for "Domain.sites". FAF can search areas that Spotlight can't. If you have a domain.sites file on the EHD Find Any File will find it. Once you find that file copy it into your Users/Home/Library/Application Support/iWeb folder. If there is no iWeb folder in the Application Support folder create a new one and put the domain file in it.
To open your domain file in Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"
tell application "iWeb" to activate
You can download an already compiled version with this link: iWeb Switch Domain.
Just launch the application, find and select the domain file you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder. So rename your domain files once they've been created to something other than the default name.
Hello OT, wow I can't believe it, I did it! It worked, everything you said worked. Your compiler, like magic. I was almost sure I didn't have that domain file saved because like you said, spotlight didn't find it. But FAF did. I muddled around a bit at first, the first time I opened up a very old version of my website. But then I realized there were multiple files called DomainSites2 on my EHD, so I went back and chose the most recent one and there it is! Im thrilled, may not seem like a big victory to most but this is a huuuuge accomplishment for this chicken plucking at the keyboard level computer genius. You should be cast in bronze, thanks a million
This is more a question for old toad or anyone who knows I did this step 10.7: Un-hide the User Library folder and now can see my library folder, but I-web is not under application support like its supposed to be, anyone know why I can't see that even after I went to the terminal and added that command?
If you're looking in the wrong Library folder as suggests there won't be an iWeb folder. Also if you've not yet launched iWeb on your Mac there won't be an iWeb subfolder in the Applications Support folder. In the latter case create an iWeb folder and place it in the Applications Support folder.
Graphically here's where you want to be looking:
