Does the behaviour continue if you visit the page and then refresh it?

If I refresh it all the icon show as read. Sometimes though they show as unread, its weird.

It sounds like a caching issue, you can try the htaccess from my guide or ozzys site to see if either help. Plus your pagespeed & yslow scores are looking really poor, applying a custom htaccess like the ones we've made will help a bit for that and hopefully for your image issues too.

Since your using dbseo I'll point you to the one I made specifically for dbseo on vb4.
