Couple of Issues

Sorry Website is https://www.stormshadowsjewelry.com

1. Please post the shortcode that you’re using. Highlight it and use the editor’s code tag. Ensure the categories which don’t display have got something in them.

2. You’ll need to fix the number of items you want per row. Currently your site is set for 5 items per row. That’s why there is a new line after every 5th item. If you want, you can change it to 4 with a snippet from here:
https://docs.woocommerce.com/document/change-number-of-products-per-row/

When you’ve settled on the number per row, the item width and/or the margin can be reduced using custom css. Please come back when you have fixed the number per row.

All categories are showing on the categories page as i have something added to them it’s on the homepage that they are missing from I have 6 categories and only 3 are showing. Here is the home page and the category page and you will see what i mean.Look down at the very bottom of the page
homepage – https://stormshadowsjewelry.com/

2. you misunderstood me I want it to show 5 columns consistently and it is not showing them consistently it is showing 4 on one line 3 on another 2 on another etc and staggering back and forth see this page.

Plus they aren’t even in line with each other.
It even does that on the category page itself when it should be showing an even number items in each column it isn’t

This is the snippet i am using i have no clue where i got it from i think it was from woo commerce before they decided that they wouldn’t help nonpaying customers even though it was their own product. I don’t know what you mean by highlight it i am a bit out of my zone with code. is why i use a snippet editor etc.

—————————-

add_filter( ‘loop_shop_per_page’, create_function( ‘$cols’, ‘return 30;’ ), 20 );

The “code” button is in the row of buttons just above the box where you type these posts. It makes code easier to read and preserves formatting. However, I don’t think your using a shortcode to display the categories, I think you’re using the Storefront Homepage Control plugin? This plugin shows 3 categories by default. You can change this number with this code:

add_filter( 'storefront_product_categories_args', 'custom_homepage_category_columns' );
function custom_homepage_category_columns( $args ) {
  $args['limit'] = 6;
  $args['columns'] = 6;
  return $args;
}

It worked for me using the “My Custom Functions” plugin, but you can try your snippet editor.

To show 5 items in a line on shop and category pages, you need to reduce the size of the items and the margin between them. To do so, try this custom css:

@media screen and (min-width: 768px) {
  .page-template-template-fullwidth-php .site-main .columns-4 ul.products li.product,
  .page-template-template-homepage-php .site-main .columns-4 ul.products li.product,
  .storefront-full-width-content .site-main .columns-4 ul.products li.product {
    width: 18%;
    margin-right: 2.5%;
  }
}

Custom css can be entered at:
Dashboard > Appearance > Customise > Additional CSS

Feel free to tweak the % values a bit to suit your taste. If you make them a bit big, the 5th item will spill over into the next row.

Regarding the add_filter() snippet, it uses the create_function() function which is deprecated, ie it should no longer be used.

Thank you so much for fixing things on my page. Wish i had you on call if I needed you, your my best-est friend.

wonder if you got a fix for something else the product on the home page don’t seem centered to me could be because i have 4 each of them and 6 of the categories down below.

and how to remove the related products from the bottom of each of my products searched but can’t find a way. I have certain products i want to show on those but they aren’t showing because the related products are there instead.

Yes, there’re not centred because there are 4 and you’ve standardised on 5 per row. Either add a fifth or set up your your site for 4 per row.

The remove_action() line to remove the related products is here:
https://docs.woocommerce.com/document/remove-related-posts-output/

thanks for the fix for related however, i have more than 4 featured set up and only 4 are still showing in the we recommend section I know this as i took out one and another that i did have popped up in its place so something is keeping either the 5th picture from popping up.
