Why did my add to cart button vanish on product pages?

Topic summary

Multiple Shopify store owners report their “add to cart” buttons have disappeared from product pages across different themes (Prestige, Brooklyn, Parallax, Avenue).

Proposed Solution:
One user suggests adding CSS code to a custom.css file:

  • Navigate to: Online Store → Themes → Edit Code → Assets
  • Create or edit custom.css
  • Add: #shopify_add_to_cart { display: block !important; }
  • Save and refresh

Mixed Results:

  • Some users confirm this fix worked for them
  • Others report the solution didn’t resolve their issue or couldn’t locate the custom.css file

Potential Causes:

  • One participant suggests subscription app widget code in product forms may be interfering
  • Issue appears after adding new products or testing subscription apps

Additional Complications:

  • Some stores show buttons on desktop but not mobile
  • “Buy now” buttons remain visible while “add to cart” is hidden, forcing customers directly to checkout and preventing multi-item purchases

The thread remains active with multiple users seeking help and sharing store URLs for troubleshooting.

Hello, the add to cart button had been working fine, however, after adding several new products, it is no longer showing on any of product pages. Any idea on what may have happened?

Hello @Maddison / @oscprofessional

I am also using the Prestige Theme and have the same issue. I think it started when I tested subscription apps.

Did you find solution appropriate for the prestige theme?

Thank you

You need to go to Online Store-Actions-Edit Code-SCROLL DOWN TO ASSETS - and then click on ADD NEW ASSET which will be custom.css and then paste this into the blank document:

#shopify_add_to_cart {
    display: block !important;
}

SAVE.  REFRESH WEBSITE.  

Hi all,

The same problem here. No add-to-cart button of any of my products. No custom.css file in my file. I did create one and tried the solution that has been given before. That did not work. My theme is Avenue and my website nordic-dekor.com

Please help me out.

I have found is an issue with. subscription apps widget code in product form code.

if you remove the app code is left behind.

pr if delete code to try remove smart payment buttons

Hey, my store is having the same issue! Someone wanted to buy multiple products, but couldn’t because there is not an ‘add to cart’ button, only a buy now/more payment options button. This then takes them straight to checkout, and when they try go back to my site to add something else, their cart empties. I’ve tried adding the custom.css with the code you put, and its not working…

The theme on my store is Parallax and here is the link to the site: https://itsbywilla.com

Any help would be much appreciated!

Could you also help me?

It only shows when someone is on a computer but not via their phone.
