Hide page title only but showing post title!

Hi Michael,
As you suggested the code below is hiding not only the page title but also the post title!
Thank you for letting me notice this.

Please there is a way to change this code in a way that I could hide only the page title but showing the post titles?

Here the code I used to hide the page title:
"P.S. In your style.css, there's this rule:
#main .entry-title {
display: none;
}
Which hides the titles for posts on that blog page of yours"

Thanks for your help.
Paddy
