How can i remove page title from woocommerce pages?

Hello,

You have a couple of options, the easiest being to simply hide it via CSS:

.product-page-title {
  display: none;
}

A better method would be to remove it via filter in your functions.php

add_filter('woocommerce_show_page_title',false);

Note that with either of these options, you’ll want to be using a Child theme so your changes don’t get overwritten: https://codex.wordpress.org/Child_Themes

Yeah so what you’ll want to do is add the body class of only the page(s) you want the title to not show on, like this:

.post-type-archive-product .product-page-title {
  display: none;
}

You can see this by opening the site in Chrome and looking in the code inspector.

My website has double headers on each page. The first header is ok but the second header which generated by Woocommerce is hidden by CSS ‘display:none;’. I wanna remove the Woocommerce header but when I’ve tryed to insert your code:
add_filter(‘woocommerce_show_page_title’,false);

but this is calls an Error:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in /web1/mcgtimber.co.uk/wp-includes/class-wp-hook.php on line 274

Try to find ‘h1’ in a code:

What did I do wrong?

I’ve found a solution.
It is needed to remove one of actions which called in woocommerce/includes/wc-template-hooks.php.
I added this string in my Functions.php and double H1 was gone:
remove_action( ‘woocommerce_single_product_summary’, ‘woocommerce_template_single_title’, 5 );
