Remove sidebar on product page

Hi Hankgotti,

You need to edit the code. Please follow the steps below

Step 1) First of all you need to go to the theme root folder ie wp-content/themes/krystal-shop

Step 2) Next go to folder template-parts

Step 3) You will find a file content-woocommerce.php there. Open this file in any text editor and replace all the code.

<?php
/**
 * Template part for displaying woocommerce content in page.
 *
 * @link https://codex.wordpress.org/Template_Hierarchy
 *
 * @package krystal-shop
 */

?>

<div class="container">
	<div class="row">
		<?php
			if(is_product()){
				?>
					<div class="col-md-12">
						<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
							<div class="entry-content">
								<div class="woocommerce">
									<?php
										woocommerce_content();						
									?>
								</div>					
							</div><!-- .entry-content -->				
						</article><!-- #post-## -->
					</div>
				<?php
			}
			else if("right" === esc_attr(get_theme_mod( 'kr_shop_styles','right' ))) {
				?>
					<div class="col-md-8">
						<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
							<div class="entry-content">
								<div class="woocommerce">
									<?php
										woocommerce_content();						
									?>
								</div>					
							</div><!-- .entry-content -->				
						</article><!-- #post-## -->
					</div>
					<div class="col-md-3 col-md-offset-1">
						<div class="woo-sidebar">
							<div class="entry-content">
								<div class="woocommerce">
									<?php get_sidebar('woosidebar'); ?>
								</div>
							</div>
						</div>
					</div>
				<?php
			}
			else if("left" === esc_attr(get_theme_mod( 'kr_shop_styles','right' ))) {
				?>
					<div class="col-md-3">
						<div class="woo-sidebar">
							<div class="entry-content">
								<div class="woocommerce">
									<?php get_sidebar('woosidebar'); ?>
								</div>
							</div>
						</div>
					</div>
					<div class="col-md-8 col-md-offset-1">
						<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
							<div class="entry-content">
								<div class="woocommerce">
									<?php
										woocommerce_content();						
									?>
								</div>					
							</div><!-- .entry-content -->				
						</article><!-- #post-## -->
					</div>
				<?php
			}
			else{
				?>
					<div class="col-md-12">
						<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
							<div class="entry-content">
								<div class="woocommerce">
									<?php
										woocommerce_content();						
									?>
								</div>					
							</div><!-- .entry-content -->				
						</article><!-- #post-## -->
					</div>
				<?php		
			}
		?>
	</div>
</div>
