Eliminate render-blocking JavaScript and CSS in above-the-fold content
 

Your page has 39 blocking script resources and 2 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

I tested my site in http://developers.google.com/speed/pagespeed and received this message, how can I fix this?

Well you can look at the theme code and what Google reported and make changes to the theme code. See what will work and let us know and it might be put in a new release

I'd suggest doing this on a test site and doing lots of backups so if you mess up you can recover and start again.

And I'm not being facetious about this. If these issues bothered me, I might try and fix the problem and give the solution to everyone, but they don't (bother me).

If you are not a coder and can't do this and really, really need it, maybe you should consider hiring someone to fix it or wait and maybe someone else will fix it.
