Remove page titles?

I just purchased this theme, Is there an option to remove titles? im trying to use no header image wide template. but would like to disable the page title.

<header class="entry-header">
		<h1 class="title-post">Home</h1>	</header>

Hello there,

Could you please try to apply the following CSS code through the Simple Custom CSS plugin or child theme’s style.css?

.page-template-page_no-header-wide .entry-header{
  display: none;

Let me know how it goes.
