Yesterday I'm confused when I looking for a <data:post.body/> or <p> <data:post.body/></p> in my blog, and than I try to arround google, and find how to handle this problem.
To shorten the time lets go to begin how way this problem.The way firt you must login to your blogger and than choice design and edit HTML.
Ok the ordinary that the code <data:post.body/> not appear is forget to cheking the little box "Expand Template Widget". While the function of to cheking the Expand Template Widget is appearing the hidden code, so with cheking that little box, all code will be display.
Ok friend, have you find that code or <data:post.body/>?? I hope you have finding. Good luck friend..!!!
