HELP!

OK Y'ALL. I AM HAVING SOME DIFFICULTY WITH MY BLOG. I CAN'T SEEM TO FIGURE OUT WHY ITS ONLY SHOWING ONE POST AT A TIME ALL THE SUDDEN... IT USED TO NOT AN NOW IT IS!!  I HAVE GONE ON AND TRIED TO FIX IT, DON'T KNOW WHY, BUT IT DOESN'T SEEM TO DO ANYTHING. SO THOSE OF YOU WHO MAY KNOW  WHATS GOING ON OR IF ITS HAPPENED TO YOU TO, PLEASE SHARE YOUR INFO ON HOW TO FIX IT! :) I DON'T WANT TO HAVE TO GO FROM ONE POST TO THE NEXT, TO THE NEXT. AND ITS ONLY BEEN THE LAST THREE POSTS, THEN YOU CAN SEE FIVE A TIME LIKE BEFORE. SO FRUSTRATING! ANYWAYS I WOULD APPRECIATE ANY ADVICE THAT Y'ALL MAY HAVE!
