Disable Page Title on ALL Pages
In UM Theme, you can remove the page title from individual pages by assigning the " Page Builder" template from Page Attributes ( Dashboard > Pages > Select the page > Page Attributes). But if you want to remove the page title from all pages, you have to use the hooks to remove title from all the pages. Or you can use WordPress Conditional Tags to selectively remove the titles.
remove_action( 'um_theme_page', 'um_theme_output_page_header' );
