Unfortunately (for them), this means you can access the content simply by clicking on the 'cached' button from a Google search.
When you get to the cached page, scroll down to the bottom of the page. All of the responses and solutions should be visible to you.
I'm very surprised that Experts Exchange and Google have not established a more 'secure' solution to this problem.
If there is a particular Experts Exchange page, and you would like to view the Google cache of that page, copy and paste the URL into a Google Search. This should expose the 'cache' link for that page.
I guess it proves that these 'Experts' + cutting edge technology (Google), doesn't necessarily = smartness.
