I am showing all the posts (few lines of whole post) on my homepage. When I validate my home page with validator.w3.org validator, it gives me errors for a post which contains images. I didn't mess with the HTML editor while creating the post and did it using Visual Editor only.
A <p> tag inside <p> tag appears.

Also, if validate the individual post it also contains errors(some are because of a rating plugin please ignore them).
