At work on a quick lunch break and had a question

When I am going into my interests I am not able to pull anything up. It is spelled right and in the past I was always able too but I realized on Monday and then I checked again today that I still couldn't pull up any blogs off my interests. I was wondering if anyone had a similar problem or who may be able to tell me who to fix it if there is a problem. Sorry I know computers just not well and I am some what new to blogging so I was not sure. Well have to go back to work but looking forward to hearing from you. Thanks! :)
