I'm developing a website and I'm getting a lot of inconsistencies with loading when refreshing a page. Clicking on links functions as expected; no issues there. The problem only occurs when REFRESHING a page. You will notice how it takes forever to load, and in some instances, refuses to load at all.

The site was built using WordPress 3.5.1 (http://wordpress.org) and Foundation 3.2.5 (http://foundation.zurb.com/).
Any assistance on this matter would be greatly appreciated. I'm out of ideas.
Thanks.
Update: This may not be IE related. The problem seems to exist in other browsers as well.
