I’m able to see the posts on your front page alright. Are you still having trouble seeing them or did you get this sorted out? If you’re still having trouble, could you please try a different browser, such as Chrome? If you can see everything OK there, could you try running Firefox in Safe Mode and let me know if that does the trick? If it does, one of your Firefox extensions/add-ons could be at fault, you can try turning them off to narrow down the culprit.
