Get rid of 'read more' link and show full post

[ Moderator note: please wrap code in backticks or use the code button. ]

I’m using theme ‘WPstart’ my website is https://www.visual-ess.com

Anyway, I understand you can get rid of ‘read-more’ from blog post to show the full blog post by changing the_excerpt(); to the_content (); but I cannot find the line to change in any of my .php pages.

the only code that I can find which includes the word ‘excerpt’ is:

/* "Read more" link: replace "[...]" with "..." in automatically generated excerpts */
function wpstart_auto_excerpt_more( $more ) {
	return '…' . wpstart_read_more_link();
}
add_filter( 'excerpt_more', 'wpstart_auto_excerpt_more' );

/* "Read more" link: add "Read more" link to custom post excerpts. */
function wpstart_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= wpstart_read_more_link();
	}
	return $output;
}
add_filter( 'get_the_content', 'wpstart_custom_excerpt_more' );
