How to fix a cart page error on my ecommerce site?

Technical Q&A
1

Hello!

May I ask if anyone has come across this cart page error before/knows how to fix it?

It comes up anytime a product is added to cart/you want to access the cart. It was working fine until today.

Hi there, @nmbda . Thanks for reaching out to the Shopify Community with your post about this error. My name is Imogen. It’s good to meet you!

I have just a few questions I’d like to ask you before we dive in more deeply:

  • Can you provide me with a link to your store so I can test this functionality out in real-time?
  • This error is occurring within the browser - have you tried to replicate this issue when using a different browser? If not, please give that a try, and let me know how it goes.
  • As this only started happening recently, have you made any recent changes to any apps within your store, or the coding for your theme?

Please, follow up with me here when you can! I’ll keep my eyes peeled for your reply!

Hey again, @nmbda ! Hope you’re doing well today!

Thank you for providing a test customer account for me to use while exploring your store. I was able to successfully reach your cart page without issue, and was also able to get to the checkout page without any issues.

Since I wasn’t able to replicate, I suspect that this issue may be a local one, or even a browser based on your end. Do you get this same issue when trying to access your cart page using a different browser or device?

Hi @Imogen_1 , we’ve now established that it appears to be the “Live Product Options” app that is causing this error; only when multiple option fields are set up for a product.

For example;

You get the cart error if you try ordering this product that has three personalisation fields set up: https://retailermerchandise.co.uk/collections/bmw-keyrings/products/bmw-new-round-metal-keyring

But the error does not happen if none/only one field was set up for a product, such as;

https://retailermerchandise.co.uk/collections/bmw-keyrings/products/new-shape-bmw-leather-fob-keyring-retailer-personalised

I reached out to the developer of the app for help as well, as it was all working fine until the other week.

Hey again, @nmbda ! Thanks for following up with us here!

It’s surprising - I’ve been seeing a lot of posts in the Community over the past few months mentioning that a third party application has had an impact like this on their cart page in some capacity. Good call on reaching out to the app developer - those are the folks that are best equipped to look into the coding of their app and determine where the hiccup is occurring.

I’m going to be marking your latest reply as a ‘solution’ so other folks experiencing similar issues can be led down the path to a resolution more quickly!

If you need any additional assistance, or have any questions for us, feel free to follow up with us here on this thread!
