Text and Links are Invisible

I think?? since upgrading to El Capitan, I now have one page on my site where the text and links are invisible. If you hover the cursor over some of the links that are suppose to be on the page, the cursor will indicate it found a link, and the link works. So the text and links seem to be there, but they are invisible.

I re-published the entire site and that didn't help. I deleted the page and published the site, then went back and recreated the page, published and that has not helped.

Here is a link to the page. If you ever the mouse on the page you'll see what I mean. The text in the Header text box works fine. The invisible text is all in one added text box.

Below is an example of what the page looks like in iWeb.
