[Theme: Amiable] Cannot Lengthen Excerpt Length

Hello! I’ve scoured the forums related to excerpts, but can’t find an answer. The theme I am using it “Amiable” by Sculpture Qode. The posts displaying on my home page are automatically truncated to 80 words, and HTML/pictures in the post will not display in this excerpt, even if they are present in the first 80 words. I would like the full post to display instead of just an excerpt. (Note: in settings, I have it set to “show full post.”)

I’ve read many tips in the forums to replace “the_except” with “the_content” in index.php, but that code isn’t there. I do see excerpt info under functions.php. Specifically, I find this:

/* Post Excerpt
*********************************************************/

// Increase the word count of excerpts
function sq_excerpt_length( $length ) {
	return 200;
}
add_filter( 'excerpt_length', 'sq_excerpt_length', 999 );

function sq_excerpt($excerpt_limit){

	global $post;

	$excerpt = get_the_excerpt();

	// Does the post have a manual excerpt
	if (!has_excerpt( $post->ID ) ) : 

		$words = explode(' ', $excerpt, ($excerpt_limit + 1));

		if(count($words) > $excerpt_limit) :
			array_pop($words);
		endif;

		return wpautop(implode(' ', $words) . '...');

	else : 

		return wpautop(get_the_excerpt());

	endif;

}

When I decrease the “200” length near the top, I see it reflected on my website. However, when I increase “200,” I see no change. After all, 200 words won’t even display in the first place – it’s only 80.

Any idea how I can either make full posts display, or have much longer excerpts, that also display pictures and HTML? I have also tried to use a plugin to override the preview length this to no avail.

Thank you!!
