Why is there a random line of code in my online store?

Topic summary

A merchant reports a random line of code appearing on their storefront and shares a screenshot; support asks which theme is in use. The image is central to understanding the visual issue.

Recommended troubleshooting and next steps:

  • Install a fresh copy of the current theme to see if the issue persists, isolating whether it’s theme-related or due to a customization.
  • If the line does not appear on the fresh copy, revert recent theme customizations that likely introduced it.
  • Before making changes, duplicate the current theme as a backup (per Shopify’s “Duplicating Your Theme” guidance).
  • If using a free Shopify theme, contact Shopify Support via the Help Center: type “Contact Support,” log in, and choose an option for assistance.

Current status: awaiting the merchant’s confirmation of the theme used and the results of testing with a fresh theme copy. No resolution yet; the thread remains open for follow-up.

Why is there a random line of code in my Shopify store. If anybody can help I would much appreciate it.

Hi @PureMist ,

Thank you for reaching out to the Community! I’m happy to provide some assistance with this request, to ensure it gets resolved. To confirm I’m fully understanding, are you able to share the theme that you’re currently using?

If you haven’t done so already, I’d encourage you to install a fresh copy of your current theme to see if this issue persists. This will allow us to determine whether the error is specific to your theme and/or due to a customization.

If you’re not seeing that line of code appear on a fresh copy of your theme, this would indicate that a customizations has been completed within the shops theme editor. Due to this, you will want to revert those changes to ensure that information no longer appears.

Prior to making any adjustments, you will however, want to create a copy of your current theme. This ensures that you have a backup, just in case any mistakes are made. To learn more about this and how you can manage your themes, you can check out our Duplicating Your Theme document.
