Assistance pls: ~50% links not working on page, iWeb 3.0.4

Question

I built a new page on a longstanding iWeb site last night, uploaded it (to my own domain hosted at Earthlink) and discovered that about 50% of the links on the page are not working, though all the links are formatted identically.
Here's the page:
http://www.MarynMcKenna.com/magazines.html
Here's how this page is built:
     - Each visible box is a shape
     - Within each shape is a text box with outline set to None
     - Each link was individually cut-pasted into Inspector (I have double-checked that none of them pasted 2x.)
     - I have checked that, in Inspector > Hyperlink, the settings for each link are:
          - Enable as a Hyperlink
          - Link to an External Page
          - Open link in new window
Also, I have checked (Command-Shift-L/Command-A) that the boxes are in the Body of the page, not in the Header, Footer etc.
When I am in iWeb, all of the links work fine.
When I upload the page and check it at Earthlink, however, the links in the larger boxes (Scientific American, Self, Annals) don't work.
I cannot see any reason why this would be going on. Any thoughts would be welcome.

Use the Inspector/Text/Text pane to adjust the inset margin to assure a uniform margin around the text in the text box.  This screenshot is without any margin:
And this is with a margin added:
