iWeb

I know iWeb is old but its been working fine until I loaded El Capitan. Now, although the iWeb page shows everything as it should, when I published it, all the Text Boxes (or anything) with a Hyperlink disappears off the actual web page.

If you hover the mouse over there the link is, its still there but whatever has the Hyperlink on it (text, photo, eat) can't be seen

Just seems a bit of a coincidence it only happened after the 'upgrade'

So how do I get back to the previous OS unless there is a fix.
