I need help with my blog [blogspot]

Hello Dps,
My blog show me double post and don't know how this happen or how to resolve it.
If you look the posts are 2 times posted in the same post.
also in this template, the home page is suppose to be like this image

but mine like you see is showing the full posts also.
I searched and didn't get to resolve it.
here the blog:

http://maghrebfun.blogspot.com/

Code (markup):

Thank you

 

The screen shot and the blog look the same to me. Where are the double posts?

 

For exemple this post:

http://maghrebfun.blogspot.com/2010/05/rapidshare-maghrebfun.html

Code (markup):

the post with its comments is doubled. (2 times). It's in arabic maybe it's why you can't see that.
Also in the home page I want the page to stop where i the image show "until here". Normaly the template is to stop there. I saw other blogs with the same template and all stop there. There home page don't show the full posts. For exemple:

http://www.thesnapclap.com/

Code (markup):

.
Please any help?

 

No one can help?

 

Hmn. Have you tweaked anything in the template code? If so, backtrack/reverse it. The safest way is to reinstall the template or (IF nothing happens), find a new one.
