How to
Remove leftover app code from your Shopify theme after uninstalling
Apps that add features to your storefront often write snippets, assets, and section references into the theme. Uninstalling removes the app, but not the code it put in your theme files. The leftovers show up as “Could not find asset snippets/….liquid” errors, unused scripts on every page, and blank app blocks in the theme editor.
Do it yourself in Shopify
- In Shopify admin open Online Store, then Themes. Duplicate your live theme first, then open the duplicate's three-dot menu and choose Edit code.
- Use the search box in the file list to find files whose name contains the app's name, usually under Snippets, Assets, and Sections. Delete them.
- Search the theme's code (theme.liquid, header, footer, product template) for the app's name and remove the render, include, section, or asset_url lines that loaded those files.
- Open the theme editor (Customize) on the duplicate and remove any app blocks that show as missing or empty.
- Preview the duplicate, check the pages that had the app, then publish it.
Things that trip people up
- Never delete files in the live theme directly. A missed reference produces an error on the storefront until you fix it.
- Some apps inject code through the theme app extension system instead of files; those disappear on uninstall on their own.
- Keep a copy of the pre-cleanup theme until you are sure nothing on the storefront changed.
Or have it done on a safe copy
With Shop Buddy in Claude or ChatGPT, say: “Remove the leftover code from Judge.me”. The change is made on a private copy of your live theme, checked, and previewed with before-and-after screenshots. You publish with one tap and can roll back with one tap. Signed in? It is also a form under Quick changes.
Get startedQuestions
- How do I know an app left code behind?
- The storefront shows a Liquid error naming a snippet with the app's name, the theme editor shows an empty app block, or a page speed tool lists a script from the app's domain.
- Is it safe to delete those files?
- Yes, when the app is uninstalled. The files did nothing but load the app. Do it on a copy of the theme, then preview and publish.
