URL could not be retrieved error

[cb2367]

While browsing the site using Chrome, it seems that after viewing a certain number of posts, that all the sudden the site no longer works until I clear the cache and cookies and reload the site. Firefox on the other hand has the same issue, but only after viewing just one post. I should maybe mention that these symptoms are occurring on the site while using a work computer. The site certainly is blocked, but it does become an annoyance when I'm wanting to check out a few forum posts and all the sudden I get an error page indicating the URL could not be retrieved, and I have to reload the page.
