Error with website coding

These are the errors in case anyone can’t access the website for any reason:

Warning: Missing argument 1 for shslideshow(), called in /home4/komandnt/public_html/wp-content/themes/Kommandant/homepage.php on line 11 and defined in /home4/komandnt/public_html/wp-content/plugins/sh-slideshow/shslideshow.php on line 291

And this is the code where the error should be in:

<?php
/*
Template Name: Home Page
*/
?>

<?php get_header(); ?>

	<div id="main">
		<div id="slideshow">
			<?php shslideshow(); ?>
		</div>

		<div id="content">

			<?php if (have_posts()) : ?>
			<?php while (have_posts()) : the_post(); ?>

				<?php the_content(''); ?>

				<?php endwhile; ?>

		<?php endif; ?>

		<div id="slideshow">
			<?php shslideshow(); ?>

		</div><!--end content div-->

		<div id="leftWidget">
		<?php if ( !function_exists('dynamic_sidebar')
		|| !dynamic_sidebar('sidebar1') ) : ?>
		<?php endif; ?>
		</div>

		<div id="rightWidget">
		<?php if ( !function_exists('dynamic_sidebar')
		|| !dynamic_sidebar('sidebar2') ) : ?>
		<?php endif; ?>
		</div>

	<div style="clear:both;"></div>
	</div>

    <?php get_footer(); ?>

in your wp-content/themes/Kommandant/homepage.php file you made some changes, you need to revert it

I tried to bring it back to the original I can’t seem to find the problem. I feel like it should be something simple but I’m overlooking it
