Layout Problems After Upgrading

HI, I just upgraded to the latest version, and noticed the there are some layout problems with my blog. The main problem is having the field information appear after the text content. I believe that I had set it up so it would appear in the beginning, but it must have been reset (which should not have happened, as people accessing the blog today and tomorrow will view the blog with the problems). Could you please check what happened and make sure this does not happen in future upgrades, please?

Thanks

Mauricio
