Cousin Blog In Problem Now

I just post about my cousin blog is up. And he just msn me and told me his blog having problem again! Oh my..I think he haven't familiar with those features yet. He is using wordpress which is kind of different from what he used previously. He used blogspot for few months and then move his blog to own domain. I gotta take some time to solve the problem for him. Althought I am not very good in this kind of stuff..but I will try my best to help him.
