problem with my blogger's main page

Hi, I am facing some serious problems with all of my blogs (on blogger.com) for the past 15 days. Whenever I make any changes to my blog like changing the template, text or widgets. Those changes don't show up on the main page instantly (it takes about 2 to 3 days) but the rest of the pages do show those changes as soon as I save changes and I can even see those changes in the preview. I have tried clearing caches and changing browsers but it is not working. Can anybody help me with this? like I said I am facing this problem for the past 15 days now so it is very frustrating for me. Thanks in advance.
